Abstract

Cognitive radio (CR) introduces the opportunistic usage of frequency bands and Orthogonal frequency division multiplexing (OFDM) is a strong candidate for CR design. Ultra wideband (UWB) radio fulfills some of the key cognitive radio requirements. Regarding the power limitations for UWB systems the main challenging issue is the impact of narrowband interference (NBI). Wavelet packet transform (WPT) is a possible choice for designing OFDM systems and has been shown as a solution to reduce interference. In this research, we explain the benefits of WPT from the literature, compare wavelet packet based MCM (WPMCM) for multiband UWB with its conventional version, and provide analytic schemes and block diagrams to implement proposed system.
