摘要

无线电波的多径传播对电信和无线电导航系统的性能产生负面影响[1，3]。当执行空间分离标准的时间和频率同步任务时，多径信号传播会增加正确同步的可能性并引入误差。多径信号的存在降低了接收信号中的信噪比，这反过来又导致同步误差的增加。文中给出了多径干扰抑制的时域和频域数学模型。与时间处理相比，频域处理降低了计算成本。时域中的抑制操作已经通过实验验证。

Compensation of Multipath Interference in a Separated Passive Time and Frequency Synchronization Systems

Multipath propagation of radio waves negatively affects to the performance of telecommunications and radio navigation systems [1, 3]. When performing time and frequency synchronization tasks of spatially separated standards, the multipath signal propagation aggravates the probability of a correct synchronization and introduces an error. The presence of a multipath signal reduces the signal-to-noise ratio in the received signal, which in turn causes an increase in the synchronization error. The mathematical models of multipath interference suppression in the time and in the frequency domain are presented in the article. Compared to time processing, processing in the frequency domain reduces computational costs. The operation of suppression in the time domain has been verified experimentally.
