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
【摘要】 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。
【Abstract】 This paper analysises and studies the importance of time delay and Doppler for signals and channel.The ambiguity function is used to characterize signal’s identity.Under wide sense stationary uncorrelated scattering(WSSUS) condition,scattering function is used to characterize identity of channel.Based on this,the best processor: delay-Doppler matched filter is proposed.Simulation has verified the effectiveness of such methods.
