Throughput-Oriented Full-Duplex Cognitive Radio Network Parameter Optimization

Full-duplex cooperative spectrum sensing (FD-CSS) is an important research field in the field of spectrum sensing. In the FD-CSS network, the secondary user (SU) senses the usage status of the authorized spectrum by the primary user (PU) through the sensing channel and then reports the perceived data to the fusion center (FC) through the reporting channel. The FC makes a comprehensive judgment after summarizing the data through the fusion algorithm. In the secondary network with SU, throughput is an important index to measure the performance of the network. Taking throughput as the optimization goal, this paper theoretically deduces and verifies the optimal data fusion algorithm in cooperative spectrum sensing (CSS), the threshold of optimal energy detection, and the optimal transmission power of SU in the secondary network. The simulation results show the correctness of the results in this paper.

Pengaruh Tingkat Keseriusan Pelanggaran, Reporting Channel, dan Retaliasi Terhadap Niat Melakukan Whistleblowing

Latar Belakang:Saat ini telah banyak terjadi kecurangan seperti korupsi, pemalsuan laporan keuangan, suap menyuap, dan lain sebagainya. Adanya kasus kecurangan ini menimbulkan banyak kerugian. Oleh sebab itu maka dibutuhkan suatu kebijakan untuk mencegah maupun mengungkap adanya kecurangan salah satunya yaitu dengan menerapkan kebijakan whistleblowing. Kebijakan whistleblowing sudah diterapkan di berbagai perusahaan seperti perusahaan Telkom, Pertamina, Astra Group, Direktorat Jenderal Pajak, dan lain-lain. Namun untuk melakukan whistleblowing seseorang akan dipengaruhi oleh berbagai faktor seperti tingkat keseriusan pelanggaran, reporting channel, dan retaliasi.Tujuan:Penelitian ini bertujuan untuk menganalisis pengaruh tingkat keseriusan pelanggaran (rendah dan tinggi), reporting channels (anonymous reporting channel dan non-anonymous reporting channel), dan retaliasi (rendah dan tinggi) terhadap niat melakukan whistleblowing.Metode Penelitian:Pendekatan pada penelitian ini menggunakan eksperimen 2x2x2 between subjects effects dengan 165 subjek penelitian. Subjek dalam penelitian ini adalah mahasiswa S1 Program Studi Akuntansi Universitas Muhammadiyah Yogyakarta. Sampel dalam penelitian ini dipilih menggunakan metode purposive sampling. Alat analisis yang digunakan adalah Analysis of Variance (ANOVA).Hasil Penelitian:Hasil penelitian menunjukkan bahwa tingkat keseriusan pelanggaran tidak berpengaruh positif signifikan terhadap niat melakukan whistleblowing, adanya anonymous reporting channel lebih efektif untuk meningkatkan niat seseorang melakukan whistleblowing, dan retaliasi rendah lebih efektif untuk meningkatkan niat seseorang melakukan whistleblowing. Dalam kondisi tingkat keseriusan pelanggaran tinggi, anonymous reporting channel, dan retaliasi rendah lebih efektif dalam meningkatkan niat seseorang untuk melaporkan tindakan pelanggaran.Keterbatasan Penelitian:Responden pada penelitian hanya terbatas mahasiswa akuntansi FEB UMY angkatan 2018 di mana mahasiswa belum memahami kondisi sesungguhnya yang terjadi dalam dunia kerja.Keaslian/Novetly Penelitian:Penelitian ini merupakan replikasi dari penelitian terdahulu dengan mengganti variabel financial reward dengan tingkat keseriusan pelanggaran dan mengubah subyek serta lokasi penelitian.

Discussion on upgrading construction of environmental protection hotline driven by AI technology

Enhancing the public’s awareness of environmental protection is an important measure to achieve the goal of carbon peak and carbon neutrality. This article takes the improvement of public participation in environmental protection as the starting point, discusses the enthusiasm of the public in environmental protection and its legal channels for reporting and complaining of environmental pollution, summarizes the achievements and existing problems of the construction of complaint channels, and proposes to improve environmental protection reports. Channel countermeasures and suggestions, build a reporting channel of environmental protection with temperature through artificial intelligence technology, increase public awareness and willingness to participate, and promote the development of environmental protection.

Pengaruh Jalur Pelaporan Dan Power Distance Terhadap Niat Melakukan Whistleblowing

This paper aims at examining the effect of wrongdoing reporting channels (anonymous and non-anonymous). Intention to report fraud via anonymous reporting channel are hypothesized to be higher than through non-anonymous reporting channel. As Hoftsede research of Indonesian culture, Indonesia has high score (78) on power distance dimention. This research uses experimental method to 152 students of Undergraduate of Accounting in UNP. By using eight-case scenarios, partispants were asked to answer the possibility to whistleblow the unethical behavior that occurred in the organization which was done by their manager or peer. The intention to report fraud via anonymous reporting channel is higher rather than via non-anonymous reporting channel. We also find that low power distance has positif impact for whistleblowing decision. Taken together, these findings contribute to the exising literature on accounting ethics.

Analyzing the effect of financial reward, personal cost and reporting channel on whistleblowing intentions utilizing an experimental study

This study aims to determine the effect of financial rewards (given and not given), personal costs (low and high) and reporting channels (anonymous and non-anonymous) on whistleblowing intentions. This study also analyzes the interaction effects among financial reward and personal cost, financial reward and reporting channel as well as personal cost and reporting channel on whistleblowing intentions. Participants in this study involve 65 finance and accounting employees of state universities in Bali. This research employs a 2x2x2 experimental design. The results of this study indicate that whistleblowing intentions are greater when given financial rewards compared to not given financial rewards, in low personal cost compared with a high personal cost, reported through anonymous reporting channels than in non-anonymous reporting channels. The results of the interaction effect indicate that greater whistleblowing occurs when given a financial reward (case at a low personal cost), through non-anonymous reporting channels. The results also confirm that higher whistleblowing intentions appear in a low personal cost through anonym reporting channels.

Cooperative Spectrum Sensing Over Imperfect Reporting Channel using an Improved Energy Detector in Multiple Antenna Based Cognitive Radio

The presentation research of agreeable variety detecting with the help of a complicated energy finder is displayed in this paper. Subjective radios contain of severa reception apparatuses. each highbrow radio distinguishes essential customer sign with improved energy location, i.E., control 'p' of the adequacy of important examples. each CR takes its very very own selection and advances to the aggregate focus. The combination hobby melds all of the stop, and sincerely the final end of the nearness or nonattendance of the vital purchaser is executed. The articulations for the synthetic alert opportunity and the likelihood of left out region were determined, and the complete mistake price is determined. Streamlining of the all out amount of CR, strength discovery control 'p' and the quantity of reception apparatuses at every CR is completed with the help of diagram and articulations thru diminishing the all out blunder fee. With the assist of numerous reception apparatuses with low SNR amongst PU-CR joins, it is validated that we can accomplish a base blunder price

Performance improvement of CSS over imperfect reporting using diversity reception in cognitive radio networks

Purpose This paper aims to discuss over imperfect reporting channel the performance of cooperative spectrum sensing (CSS). It is investigated that imperfect reporting channel introduces some lower bound in false alarm probability (Pf). The lower bound of probability of false alarm linearly increases with the probability of reporting error. Design/methodology/approach To solve this problem, a transmit diversity-based CSS method is proposed, and to improve the detection performance, square law selection (SLS) diversity is used. Findings It is observed that detection probability increases up to 11.55 per cent when SLS diversity is applied, and lower bound Qf decreases up to 80 per cent when transmit diversity is applied. Originality/value No literature is available to the best of the authors’ knowledge that measures the performance of CSS with respect to parameters as reported in this paper.
