Abstract	A hybrid direct-sequence (DS)-multiband ultra-wideband (UWB) multiple access system is proposed and a simple error analysis is presented for the system considering a multipath channel. The error analysis facilitates to obtain simple-to-evaluate Improved Gaussian approximation (SIGA), a method that has previously mainly been used in DS-CDMA. In this paper, we show that the method can also be used effectively for UWB multiple access systems. It is shown that despite having the same processing gain, which is some multiple of the multiplication of the number of frequency bands in use and pulses per bit, different combinations of the parameters result in different performances. Considering Rake type receiver, results are shown for both maximal ratio combining (MRC) and equal gain combining (EGC) and the validity of standard Gaussian approximation (SGA) is examined for various combined paths. The theoretical results are validated by Monte Carlo simulations
