摘　　要：为深入研究基于PSWF的非正弦通信技术应用于短波通信中的特性,在分析选择短波信道模型和阐述非正弦通信调制解调原理的基础上,对短波信道特性给非正弦通信的影响进行了理论分析;在利用Simulink对非正弦短波通信模型实现的基础上,对相对时延和误码率之间的关系、传输路径数目不同和误码率之间的关系以及通信中采用不同能量聚集性的PSWF脉冲组和误码率之间的关系进行了仿真分析。结果表明:传输路径的增加使系统的误码率上升;选择能量聚集度好的脉冲组可以提高系统可靠性;相对时延增加系统可靠性并不随之变差。For further studies on the characteristics of PSWF-based non-sinusodial communication in HF channel,the effects of the characteristic of HF channel on non-sinusoidal communication are analyzed in theory,based on making choice of HF channel model and expounding the principle of non-sinusoidal communication modulation and demodulation. A model of Non-sinusodial HF Communication based on PSWF has been established on the basis of Simulink. The simulations have been completed,which is about the relationship between BER and relative delay, BER and transmission path number,the BER and the energy aggregation Level of PSWF pulse groups. The results show that：the BER will be rise as the transmission paths increasing;the pulse groups with high energy aggregation Level can reduce the BER;the BER will not necessarily increase as the relative delay increasing.
