Abstract :
In this paper, a combined pulse position modulation (PPM), differential BPSK and multi-pulse modulation (MPM) have been proposed for the multiple access system in order to increase the total data rate and improve the error performance by using the same number of pulses. With these schemes, the modulated pulse can be used for transmitted more than one bit data depending on the level of MPM and PPM modulation. Moreover, the error performance has been improved because the energy per pulse has increased for same Eb/No. In addition, the simulation results show that the total throughput performance of the proposed system is improved by nearly 4-5 times compared to the conventional TR-UWB system
