摘要

本文提出了一种多波段正交PSWF脉冲集设计方法。所设计的脉冲集在满足FCC频谱掩模要求的同时，具有较高的频谱利用效率，无需移频或附加滤波。在此基础上，提出了一种基于正交脉冲集的多PPM调制方案。在该方案中，每个用户被分配一个不同的正交PSWF脉冲。在理想条件下，可以完全消除系统的MAI。从理论上推导了该方案SER性能的解析表达式。仿真结果表明，该系统比传统的单高斯脉冲超宽带系统具有更好的误码率性能。此外，多波段正交PSWF脉冲可以有效地克服系统的MAI。

Multiband Orthogonal PSWF Pulses Used for M-ary PPM Ultra-Wideband System

In this paper, we proposed a multiband orthogonal PSWF pulse set design method. The designed pulse set has a high spectrum utilization efficiency while meeting the FCC spectral mask without frequency shifting or additional filtering. Based on this, a Mary PPM modulation scheme using the orthogonal pulse set is developed. In this scheme each user is assigned a different orthogonal PSWF pulse. And the MAI of the system can be eliminated completely under ideal condition. An analytic expression of the SER performance for the scheme is derived theoretically. Simulation results show that the proposed system has a better BER performance than the traditional UWB system employing single Gaussian pulses. Moreover, the multiband orthogonal PSWF pulses are effective in overcoming MAI of the system.
