An Optimal Power Allocation Scheme for Cooperative Communication Network with Non-Orthogonal Multiple Access

Abstract

Cooperative communication is helpful in improving the capacity of the modern telecommunication by utilizing antennas for applying the spatial diversity approach. Cooperative communication quality of service is highly dependent on allocation of resources which significantly focus on power control and the selection of relays. Non-orthogonal multiple access (NOMA) base model performance is demonstrated in this paper for enhancing the efficiency of the spectrums and achievable sum rate for the cooperative communication systems. Optimized allocation of power in cooperative communication is targeted by applying the Satin bowerbird optimization (SBO) algorithm. Using this algorithm, power allocation factors that are used in the transmitted signal are selected optimally by considering minimum outage probability as an objective function. The performance of the proposed SBO based power allocation is compared to the scenario when SBO is absent and results incorporates outage probability and achievable sum rate.

Frequency Response Analysis of the Parallel-plate Transmission Line using Various Conductors

“…Over the past decades, various studies have been implemented that concern material modification in the parallel-plate transmission line [4,5,6,7,8,9,10]. This paper differs from said studies such that the researchers are exclusively tackling the impacts of the outer conductor material on the frequency response of the aforementioned transmission line.…”
