PSWF非正弦时域正交调制信号短波信道研究
Research on Time-domain Nonsinusoidal Orthogonal Modulation Signal Based on PSWF in HF Channel
摘要
Abstract
The orthogonality of the PSWF impulses plays an important role,when the nonsinusoidal time-domain orthogonal modulation signal based on PSWF is demodulated.Theoretical analysis and simulation analysis on effects of multipath delay,attenuation and number of modulation channels have been done after the HF Channel model and the principle of nonsinusoidal time-domain orthogonal modulation are introduced.The results show that the effects of multipath delay on orthogonality of the PSWF Impulses change regularly and a cycle is a code time.The attenuation plays a main role in the effects of all factors.The effect of the number of modulation channels tends to be smooth as it increases.关键词
