Sidelobe Suppression Performance of NCSP-OFDM for Cognitive Radio System

Abstract

This paper evaluates performance of sidelobe suppression of N-continuous OFDM, Spectrum sculpting precoder (SSP), NCSP-OFDM for a cognitive radio system. The experimental results show that NCSP-OFDM can form a spectral notch as sharply as SSP and does not degrade its error rate in both AWGN channel and multipath fading channel.
