摘要

提出了一种简单的基于差分检测器的码移键控/扩频自同步系统。在该方法中，使用由曼彻斯特编码伪噪声序列和非曼彻斯特编码伪噪声序列组成的一对。直接利用这些序列之间的互相关特性来代替延迟锁环的s曲线。评估了加性高斯白噪声(AWGN)信道下的以下性能:(1)跟踪误差(抖动)性能;(2)考虑抖动的误码率(BER)性能。结果表明，该系统的性能优于外部同步系统。

A simple self-synchronization system for CSK/SS

A simple self-synchronization system for code shift keying/spread spectrum (CSK/SS) with the differential detector is proposed. In the proposed method, a pair consisting of the Manchester-coded pseudo-noise (PN) sequence and the nonManchester-coded PN sequence is used. The cross-correlation characteristic between these sequences is used instead of the S-curve of the delay lock loop (DLL) directly. The following performance under the additive white Gaussian noise (AWGN) channel is evaluated: (1) the tracking error (jitter) performance; and (2) the bit error rate (BER) performance that takes into account the jitter. As a result, it is shown that the performance of the proposed system is better than that of the external synchronization system.
