英文摘要In non-cooperative communication, the code frequency, the pulse shaping filter and other prior parameters are unknown to the receiver, which increases the challenge of non-cooperative receiving system design. A straightforward method may estimate these parameters in advance following traditional receiving systems. Estimation errors will undoubtedly be involved and passed between stages, which will decease system performance, especially in low signal-to-noise ratio (SNR) scenarios. To address this problem, this paper constructs a carefully designed optimization function for timing estimation that combines both the code frequencies and the timing parameters from multiple chips. Consequently, a feedback-based tracking model is proposed to solve such an optimization function. Finally, extensive simulation results validate the efficiency of the proposed method, which achieves ten times better accuracy than the traditional method and can partially overcome the influence of code frequency deviations.
