Abstract

This paper investigates the performance of different digital modulation techniques in Multipath fading channel interface air. The paper describes characteristics of wireless communication channels with emphasis on fading channel. This study examines the inherent attributes of the digital modulation schemes to overcome the impairment introduced by the channel. The channel was modeled and simulated using 6 rays. The evaluation of the different modulation techniques was carried on the modeled multipath channel. This was carried out to understand the contributions of channel characteristics to effective wireless communication. The BER for simulated modeled channels agreed with the theoretical results. It was also observed that multipath fading channel characteristic limits the data rate in wireless communication.
