Abstract

In this paper we analyze the Bit Error Rate (BER) performance of Cognitive Radio Physical layer over Rayleigh channel under different channel encoding schemes, digital modulation schemes and channel conditions. The system outperforms with BPSK modulation technique as compared to other digital modulation schemes and the system is highly effective to combat inherent interferences under Rayleigh fading channel. The system shows improved BER on using encoding schemes with error rate reduced by 10% using Reed Solomon (RS) encoding, 95% reduction on using Convolution encoding and 98% error reduction on applying RS with Convolution encoding. It has been anticipated from the simulation study that the performance of the communication system degrades with the increasing of noise power.
