UWB Channels can be measured by sounding the channel with pulses, and thereby obtain the impulse response. Multipath components have different waveforms depending on the type of transmitter and receiver antennas used and the angles of transmission and reception. A modified deconvolution technique is introduced to extract the UWB channel response. The application of deconvolution techniques results in resolving multipath components with waveforms different from that of the sounding pulse. Resolving more components should improve the design of the rake receiver. Accurate characterization for the impulse response of a UWB communication system facilitates performance evaluation studies such as simulating the effect of pulse shaping.
