A study on the performance of multifilter bank based Cognitive Radio transceiver for multi-user applications

Cognitive Radio (CR) transceiver that can offer adequate data rate and multi-user support for future wireless networks is a promising technology for reliable and spectrum efficient mobile communication. Orthogonal Frequency Division Multiplexing (OFDM) and scalar wavelet based schemes have been proposed as physical layer techniques for CR. This paper proposes multiwavelet packet based multi carrier multiple access scheme as an equally promising candidate for multi-user CR networks and using existing orthonormal multiwavelets, the performance of the proposed system is evaluated in terms of bit error ate and computational complexity.
