Abstract

In this paper, we propose Direct Sequence (DS) Code Division Multiple Access (CDMA) for Ultra-Wide Bandwidth (UWB) impulse radio communications. The main design issues are outlined and performance is estimated in additive white Gaussian noise (AWGN). The performance of DS/CDMA is compared with that of Time Hopping (TH) using pulse position modulation (PPM). Both uncoded and convolutionally coded transmissions are considered.
