Millimeter-wave (MMW) frequencies (30–300 GHz), located between the microwave and infrared (IR), are promising solutions for the increasing demand of high data rate applications, UHD multimedia, HD gaming, security, surveillance, and the emergence of 5G Internet of Things (IoT). In this article, we experimentally demonstrated MMW wireless communication link using InGaAs p-i-n photomixer and commercially available telecom components at W-band (75–110 GHz). The photomixer was excited by two 1.5 µm lasers via standard telecom fiber optics, to generate frequency difference at W-band. QPSK modulated signal transmitted by the photomixer and received horn antenna integrated MMW mixer and analyzed using a spectrum analyzer and Vector Signal Analyzer (VSA) software.

Redundant Data

The growing interest towards wireless communication advancement with smart devices has provided the desired throughput of wireless communication mechanisms. But, attaining high-speed data packets amenities is the biggest issue in different multimedia applications. Recently, OFDM has come up with the useful features for wireless communication however it faces interference issues at carrier level (intercarrier interferences). To resolve these interference issues in OFDM, various existing mechanisms were utilized cyclic prefix, but it leads to redundancy in transmitted data. Also, the transmission of this redundant data can take some more power and bandwidth. All these limitations factors can be removed from a parallel cancellation mechanism. The integration of parallel cancellation and Convolution Viterbi encoding and decoding in MIMO-OFDMA will be an effective solution to have high data rate which also associations with the benefits of both the architectures of MIMO and OFDMA modulation approaches. This paper deals with this integrated mechanism for efficient resource allocation and power consumption. For performance analysis, MIMO-OFDMA system is analyzed with three different approaches likeMIMO-OFDM system without parallel cancellation (MIMO-OFDMA-WPC), MIMO-OFDMA System with parallel cancellation (MIMO-OFDMA-PC) and proposed IMO-OFDMA system with parallel cancellation and Convolution Viterbi encoding/decoding (pMIMO-OFDMA-PC &CVed) for 4x4 transmitter and receiver. Through performance analysis, it is found that the proposed system achieved better resource allocation (bandwidth) with high data rate by minimized BER rate and achieved least power consumption with least BER.

The terahertz wave is a kind of electromagnetic waves which locates between millimeter waves and infrared lightwaves, and the frequency range is 0.14THz~10THz. Terahertz is used as a carrier wave to communicate with each other because it has large bandwidth which can support Gbps wireless data rates. Therefore, terahertz communication technologies become research hot spots in recent years. However, its still rare in MAC protocol of terahertz ultra-high data-rate wireless networks at present. In order to realize wireless access of ultra-high data-rate under the condition of terahertz carrier frequency, a novel MAC protocol is proposed in this paper. The improved MAC protocol which makes the maximum data rates reach up to 10Gbps or higher is designed by new MAC control mechanisms, new time-slots allocation schemes and new superframe structure. Theoretical analysis and simulation results show that the new proposed MAC protocol of terahertz ultra-high data-rate wireless networks can operation normally, and the maximum data rate can reach up to 19.2Gbps. This maximum data rate is 2 times higher than 5.78 Gbps which IEEE 802.15.3c can achieve.
