Throughput Analysis in Cooperative Spectrum Sensing Network using an Improved Energy Detector

Abstract

In this paper, we have analyzed the performance of an average channel throughput analysis using an improved energy detector (IED) under non-fading environment (AWGN channel) in cooperative spectrum sensing (CSS) network. The performance analysis is evaluated using different fusion rules (k=1+n and k=M-n) at fusion center (FC). The error rate is considered in reporting channel (R-channel) to show the effect of an error on the average channel throughput. Our simulation results gives the analysis of an average channel throughput for various values of detection thresholds, number of secondary users (M), and error rates in R-channel using different fusion rules at FC. The average channel throughput performance comparison between error free and error present in R-channel is provided using the MATLAB simulations. Finally, we have calculated an optimal number of secondary users to maximize the average channel throughput for different fusion rules.
