已知信道统计特性的时延—多普勒匹配滤波

Delay-Doppler Matched Filtering with Known Statistics of Channel

该文研究了时延和多普勒在信号和信道分析中的重大作用,用模糊度函数表征信号的时延—多普勒特性,广义平稳非相关散射条件下用二阶统计参量—散射函数表征信道的时延和多普勒模糊特性。在此基础上,导出了时延—多普勒匹配滤波器,并得到有效的试验结果。

This paper analysises and studies the＇importance of time delay and Doppler for sigr,als and chan- nel. The ambiguity function is used to characterize signal＇ s identity. Under wide sense stationary uncorrelated seattering（WSSUS） condition, scattering function is used to charaeterize identity of channel. Based on this. the best processor ： delay-Doppler matched filter is proposed. Simulation has verified the effeetiveness of such methods.
