Abstract
Aiming at the current problem of scarcity and low utilization of radio frequency resources, idle sub-channel judgment based on energy detection is studied on universal software radio peripheral (USRP) platform. An efficient frequency-division multiplexing system is built in the case of evading authorized users during the transmission process and giving the presence of the primary user. Moreover, the cognitive algorithm based on energy detection and blind detection of SEFDM signals is given, the ID-FSD algorithm is introduced, and the performance of the proposed receiver-end ID-FSD detection algorithm is verified. This algorithm can not only improve the frequency utilization rate but also guarantee the BER performance. In addition, this algorithm is applied to realizing the cognitive radio spectrally efficient frequency-division multiplexing system on USRP platform.
