In spread spectrum receivers, due to dynamic factors such as the relative motion between transmitter and receiver and the instability of clock, there is code-frequency offset between the received and the local PN codes. The formulas for the correlation function of PN code in the presence of code-frequency offset and its mean are derived and verified in this paper. And then the effects of code-frequency offset on the correlation of PN codes, including spread of main-lobe, shift and loss of peak are studied. The...

在扩频接收机中,受发射机和接收机之间的相对运动和时钟频率不稳定等动态因素的影响,接收伪码和本地伪码之间会存在一定的频移。本文推导并验证了频移条件下的伪随机码信号相关函数及其均值公式,在此基础上分析了频移对伪随机码信号相关函数的影响,包括主瓣展宽、峰值移位和损耗等现象。本文的结论为高动态接收机伪码同步技术提供了理论基础。
