概要
- 論文の詳細を見る
In this paper, two new modulation schemes, Multi-Pulse Modulation (MPM) and Differential Multi-Pulse Modulation (DMPM) have been proposed in order to increase the total data rate and improve the error performance. By these schemes, the modulated pulse that had been used for transmitting only one data bit in each pulse-pair in conventional TR-UWB system, can be used for transmitting more than one bit data depending on the level of modulation. Moreover, the error performance has been improved by these new modulation schemes because for the same E_b/N_0, the energy per pulse has increased. In addition, these new modulation schemes are applied to a multiple access system. The simulation results show that the total throughput performance of the proposed system has been improved, nearly 2-4 times when compared to the conventional TR-UWB communication system.
