DS-PPM ultra-wideband communications with BCH Coding

Ultra-wideband (UWB) transmission for short-range wireless communications has recently drawn great attention. This is due to advantages such as high speed, immunity to multipath fading, low cost, and the ability to coexist with narrowband wireless systems. In this paper, we improve the performance of a direct sequence spread spectrum pulse position modulation (DS-PPM) UWB system via the addition of a Bose-Chaudhuri-Hocquenghem (BCH) code. Both single user and multiple-access performance over an additive white Gaussian noise channel is considered.
