A novel modification method for IEEE802.15.3a channel model [UWB]

Based on the all-rake receiver theory, a modification method for UWB multipath channel models is proposed. In accordance with the UWB pulse shaping scheme, it can modify the IEEE802.15.3a multipath channel model into a tapped-delay-line channel model with specific center frequency and multipath resolution. The modified channel model provides a design reference and simplifies the system analysis and simulation. As an example, the modification for a typical UWB pulse has been done, and the statistical characteristics of the modified channel model have been analyzed.
