Design Of Improved Transmultiplexers For Cognitive Radio Applications

P. Kalpana Devi , Dr. R. S. Bhuvaneswaran

Abstract :

Transmultiplexers (TMUXs) allow different users to share a common channel to have distinct bandwidths allocated for different applications. The signals are multiplexed together and transmitted in a single channel. Existing designs provide non linear optimization with large no. of coefficients and high degree of complexity. The improved transmultiplexers structure is designed for demultiplexing the FDMA channels of frequency band allocation in cognitive radio applications This structure must have the capability of extracting multiple channels of distinct bandwidth corresponding to the different communication standards by the cosine modulation filter bank with near perfect reconstruction technique . Design analysis proved that the optimum device utilization is achieved for the filter bank approach in the improved transmultiplexers.
