Performance of UWB PPM in residential multipath environments

A performance analysis of a ultra-wideband (UWB) wireless system transmitting binary pulse position modulated (PPM) data over a realistic multipath indoor channel is presented. In this paper we use an autoregressive (AR) channel model to represent the small scale fading introduced by the multipath environment. We also include the effects of large scale fading with a lognormal shadow fading model for the path loss (PL). New parameters for the AR model are proposed, and computer generation of the channel frequency response is described. Numerical results using these new parameters are presented, characterizing the performance at several separation distances between transmitter and receiver in the line of sight (LOS) and the no line of sight (NLS) cases. The results may be the base for field design system applications, such as a UWB home network.
