ABSTRACT:
In accordance with the present invention, a system and method that exploits the efficiency of the spectrum utilization is provided. The proposed technique, which is referred to as dispersed spectrum utilization, is based on the idea of transmitting the information over multiple dispersed bands in contrast to the current wireless communication systems which transmit the signal over a single band. A cognitive radio transceiver is developed for the implementation of this dispersed spectrum utilization technique.
