Abstract

A modified M-ary time hopping pulse position modulation (TH-PPM) ultra wideband communication system is proposed in this paper. The system performance over additive white Gaussian noise (AWGN) channel is evaluated in the condition of perfect time synchronization and correlation receiver. In this system, the modified M-ary modulation is obtained by combining signal partitioning with the pulse position modulation. Three signal partitioning, ungerboeck partitioning (UP), block partitioning (BP) and mixed partitioning (MP), are investigated in this work. The modified scheme can make no increment in system complexity compared to the conventional M-ary time hopping pulse position modulation. To some extent, it can improve the system performance. The computer simulation and analysis shows that the modified M-ary TH-PPM system outperforms the conventional M-ary TH-PPM system
