AbstractIn this paper, we study non-uniform multilevel quantization problem in cognitive radio networks (CRNs). We consider a practical collaborative spectrum sensing (CSS) scenario in which secondary users (SUs) cooperate with each other to decide about the presence of the primary user (PU). We consider a cooperative parallel access channel (CPAC) scheme in reporting channels in which SUs transmit their quantized data to fusion center (FC) for the final decision. Also, we evaluate the final summation-based decision statistic and Kullback-Leibler (KL) divergence performance criterion in the Rayleigh fading channel and additive Gaussian noise. We compare the non-uniform quantization scheme performance with the uniform one and illustrate the sensitivity of the provided quantization scheme to average error probability of symbols. Furthermore, the effect of the collaboration in the CPAC scheme on performance of the distributed sensing compared with non-cooperative scheme is investigated.
