为了从分相码流中提取时钟信号,本文介绍了三类非线性同步器,它们都能产生时钟频率分量及其谐波。本文推导出估算时钟频率分量的功率和由限带白噪造成的定时误差公式,并且指出有几种同步器的性能与信号统计特性无关。分相码的这一重要优点是以加宽频带换取的。
In order to extract the clock signal from the fractional code stream, this paper introduces three types of nonlinear synchronizers, which can generate the clock frequency components and their harmonics. This paper deduces the power for estimating the frequency components of the clock and the timing error caused by white-band limiting, and points out that there are several types of synchronizers whose performance is independent of the signal statistics. This important advantage of the fractional code is to broaden the band in exchange for.
