For multi-source relay-based cooperative communications, it is widely believed that Complex Field Network Coding (CFNC) achieves better throughput performance than Physical-layer Network Coding (PNC). However, traditional CFNC schemes suffer a considerable loss on the performance of symbol to error ratio (SER) and peak-to-average power ratio (PAPR) as the number of source nodes increases. In this...
This Paper Investigates the effect of probability distribution equalization techniques on reducing the PAPR in NCOFDM widely used in Cognitive Radio Systems, and proposes the use of Arithmetic Coding to be used in NCOFDM for PAPR reduction. Simulation results show that the proposed Arithmetic Coding scheme can greatly reduce the PAPR of the NC-OFDM system. Furthermore, the results show that the Arithmetic...
