dc.description.abstract Non-contiguous orthogonal frequency division multiplexing (NC-OFDM) is an efficient transmission technique in cognitive radio systems. It provides high bandwidth utilization and robustness against time dispersive channels. However, high sidelobe power and peak to average power ratio (PAPR) are the two main challenges in NC-OFDM systems. The conventional research on the literature treats these two problems individually as two independent problems, while in this paper we focus on the general performance improvement in terms of the two problems together. The general performance of all the techniques are studied and compared together through both theoretical analysis and numerical simulation. The simulation results are discussed based on the following metrics: sidelobe power, PAPR, bit error rate (BER) and system complexity. Results confirm that hybrid precoding technique is considered an optimum for all the performance measured metrics. en_US
