Abstract :
This paper analyzes the multipath behavior of FM-UWB signals and more particularly the effect of frequency selective fading upon the sub-carrier signal level in the FM-UWB receiver. The performance with CM1-CM4 channels is investigated and illustrated with MATLAB simulation results. Good and bad propagation channels for FM-UWB communication systems are identified. The effect of frequency selective fading is mainly determined by the channel transfer at the edges of the FM-UWB signal´s bandwidth. It is shown that multipath is beneficial for the FM-UWB receiver performance.
