在分析 PSWF 脉冲的最佳时域能量聚集性和频谱灵活可控性的基础上,提出了满足 FCC(Federal Communications Commission)频谱掩膜要求的 UWB 脉冲波形优化设计方法,并将该方法应用于多进制 TH-PPM 超宽带系统中,理论计算了基于 PSWF 脉冲的多进制 PPM-UWB 系统的符号差错率公式.与高斯脉冲进行比较,采用 Systemview 可视化仿真平台进行了仿真.仿真结果表明,基于 PSWF 脉冲的 UWB 系统符号差错率性能要明显优于 Gauss 脉冲.在给定 SER 的前提下,使用 PSWF 脉冲的 UWB 系统能够容纳更多的用户.

In this paper, the high spectrum utilization efficiency and the flexibility of PSWF was analyzed. Based on this, a method meeting the FCC spectral mask was proposed and it was used in a M-ary TH-PPM UWB system. Both the analytic expression of the SER performance for the scheme and the simulation based on Systemview were derived theoretically. Simulation results showed that the proposed system had a better BER performance than the traditional UWB system employing single Gaussian pulses. Being given the premise of the value of SER, the UWB communication systems with PSWF pulse can accommodate more users.
