Summary: | Timing-jitter is an important index of timing recovery algorithm. This paper describes impact-factors of timing-jitter in an AWGN channel and discovers that input noise have great influence on it, proposed an improved timing recovery method for adding a loop gain to reduce it. Simulations demonstrate that a timing recovery with loop gain can have performance superior to that of without it, and got the conclusion that add loop gain at the range of 0.1 to 0.3 both timing jitter and timing recovery points can reach minimum values. Better yet, when choose a loop gain at 0.1, timing jitter decrease from ±0.2 to ±0.08, and system’s error rates also have obverse decrease. |
