Multipath fading causes decrease of system performance in wireless communication environment. Therefore, intelligent high-speed communication system which can effectively reduce ever-changing multipath interference is necessary in order to provide high quality data service. In this paper, we analyzed channel performance of intelligent UWB communication system in indoor radio fading environment that consider amplitude characteristic of channel. Also, we improved performance of system that it is decreased in fading environment employing rake receiver and convolution encoding techniques.
