Add to ORKGThe Cognitive Radio (CR) enables spectrum aware communication protocols to sense the spectral environment and use this information to opportunistically provide wireless links that meet the user communications requirements optimally. CR techniques can be applied to Multi-band OFDM based UWB systems in order to continuously detect the presence of primary users, and accordingly shape the transmitted signal spectrum to allow peaceful coexistence between the primary and secondary systems. In this paper, the cross layer design approach and challenges for cognitive radio functionalities to enhance its efficiency in dynamic spectrum access management are discussed. Spectrum sensing and scheduling challenges as well as spectrum shaping challenges ar...
