摘要 针对使用窄脉冲传输数据的超宽带系统,依据修正Hermite函数的正交、无直流分量等特性,提出了一种基于正交UWB脉冲的PSM超宽带系统。仿真结果表明该设计能改善系统性能,降低误码率。 In view of the Ultra wide band （UWB） system which transmits data information using ultra - short pulses, this paper presents a pulse shape modulation UWB system based on orthogonal UWB pulse on the basis of the orthogonality and no direct component characteristics of modified Hermite polynomial function. The simulation result indicates that the method can decrease the bit error rate.
