VHDL implementation of MIMO based FSK for reconfigurable applications

Cognitive Radio is the best technology to improve spectrum utilization of wireless communications by exploiting under-utilized licensed spectrum. The core concept of cognitive radio is designed to address the problems faced in allocating spectrum efficiency and it provides wireless users to adapt their spectrum (band of frequencies) operating factors and sharing spectrum with the help of information from the adjacent radio environment. This paper deals with the cognitive radio (CR) sensing, analysing, understanding and deciding. This type of technique has its own potential to further improve the performance of cognitive networks, especially for spectrum sensing. The proposed system implements FSK modulation designed and debugged in modelsim using VHDL. Also reconfigurable CR channel are created which adapts low, medium and high traffics. Core concepts to handle the high traffic handling is created in the CR module and analysed with the simulation results. Expected results to solve the high traffic user with the use of reconfigurable MIMO FSK transmitter and CR.
