Abstract :
This paper proposes an adaptive channel selection method that reduces signal distortion due to frequency selective fading and thereby improving the performance of mobile communication. In this method a channel is adaptively selected by estimating current channel condition with mean square decision error as a measure. This selected frequency channel corresponds to the channel in which the delayed signals add-up inphase. Hence, BER performance is improved with the proposed scheme. Computer simulation results show the effectiveness of the proposed scheme for a system with multiple terminals and also for a multiple base station (cellular) system
