Abstract

Cooperative spectrum sensing can improve detection performance of cognitive radio (CR) when the channel is in severe fading and shadowing environment. In this paper, we have designed cooperative spectrum sensing-based wideband CR system including transmitter and receiver. Each CR user marks the spectrum availability through energy detection and gets the sub-basis function through doing Inverse Fast Fourier Transform (IFFT) with the product of the spectral marker vector and the random phase vector. The cooperative spectrum sensing can be realized by cascading the sub-basis functions of all the users. The simulation results have shown that the proposed system can avoid the interference caused by the primary user and outperform the spread spectrum system.
