Hardware Impairment

In this paper, we introduce a half-duplex (HD) energy harvesting (EH) relay network over the different fading environment with the effect of hardware impairment (HI). The model system was investigated with the amplify-and-forward (AF) and the power splitting (PS) protocols. The system performance analysis in term of the outage probability (OP), achievable throughput (AT), and bit error rate (BER) were demonstrated with the closed-form expressions. In addition, the power splitting (PS) factor was investigated. We verified the analytical analysis by Monte Carlo simulation with all primary parameters. From the results, we can state that the analytical and simulation results match well with each other.

End To End

The end-to-end spectral efficiency and bit error rate (BER) of an amplify-and-forward (AF) radio relay chain employing orbital angular momentum (OAM) multiplexing is presented. The inherent divergence of a beam carrying OAM is overcome by means of a lens. Modelled and measured inter-modal crosstalk levels are incorporated into the analysis. The results show that an end-to-end spectral efficiency of up to 8 bits s −1 Hz −1 is achievable using four OAM modes to multiplex four parallel data streams over 20 hops, provided that the detrimental effects of inter-modal crosstalk are mitigated. The spectral efficiency is expected to scale further by using more OAM modes. The BER profile along the relay chain is analysed for each of the four OAM modes.

Primary Interference

In this paper, Bit Error Rate (BER) of Orthogonal Frequency Division Multiplexing (OFDM) based cognitive radio network is analyzed in the presence of Primary User Interference (PUI). Since, the PUI signal affects only few subcarriers of the OFDM signal, it can be modeled as a sparsity vector. In this network model, half duplex Amplify and Forward (AF) relaying is considered in the absence of direct link. Further, it is assumed that the network is operating in the overlay mode, thus the primary user transmitted signal act as interference at secondary user relay and destination nodes. In this paper, the PUI is mitigated using convex optimization. Bit Error Rate (BER) is analyzed using Quadrature Phase Shift Keying (QPSK) Modulation and Quadrature Amplitude Modulation (16-QAM). Simulation results conclude that after primary interference suppression, the performance of the proposed system is significantly improved.

<p>The performance analysis for the MIMO-FSO systems employing EGC technology over Lognormal-Rician turbulence channels with pointing errors is important. However, the results so far are greatly limited since the PDF of Lognormal-Rician turbulence channels is not analytic, even for the SISO systems. In this paper, we propose a new method to approximate the sum of lognormal-Rician turbulence channels with Rayleigh pointing errors. Based on the developed formula, the approximate closed-form expressions of ergodic capacity, outage probability, and bit-error rate are derived. Numerical results demonstrate the accuracy of the proposed approach.</p>
