An optimization technique for simultaneous reduction of PAPR and out‐of‐band power in NC‐OFDM‐based cognitive radio systems
Noncontiguous orthogonal frequency division multiplexing (NC‐OFDM)‐based cognitive radio (CR) systems achieve highly efficient spectrum utilization by transmitting unlicensed users' data on subcarriers of licensed users’ data when they are free. However, there are two disadvantages to the NC‐OF...
