This paper analyzes the Bit Error Rate performance of Cognitive Radio Physical layer over Rician channel with AWGN noise under different channel encoding schemes, digital modulation schemes and channel conditions. The system outperforms with Reed Solomon along with convolution encoding for BPSK modulation technique as compared to other digital modulation schemes and the system is highly effective to combat inherent interferences under Rician fading channel. The system shows improved BER on using encoding schemes with error rate reduced by 10% using Reed Solomon encoding, 91% reduction on using convolutional encoding and 99% error reduction on applying Reed Solomon with convolution encoding.
