Abstract :
In this paper, a hybrid direct sequence (DS) multi-band ultra-wideband (UWB) system compared with a hybrid direct sequence time hopping (DS/TH) impulse radio (IR) UWB system is proposed and its BEP is presented. This error analysis facilitates to obtain simple-to-evaluate and accurate error probabilities based on Holtzman´s simplified improved Gaussian approximation (SIGA). System performance is also presented for various duty-cycles of the signals considering equal and unequal powers of the users and the validity of standard Gaussian approximation (SGA) is examined. The theoretical results are validated by Monte Carlo simulation.
