Timing-jitter-suppressed partial-response signals

In this paper the timing-jitter-suppression problem for partial-response systems is considered. In particular, by imposing the zero-derivative constraint on five practical classes of partial-response signals timingjitter suppression is achieved. For this purpose, an overall frequency-response design procedure is developed, and a minimum-bandwidth signalling scheme is introduced which results in a triangular filter followed by a tapped delay line, where the choice of taps depends on the type of partial-response signal used in the system. By introducing a recursive equaliser in the receiver the equaliser structure is redesigned and it is observed that some partial response signals result in an improved performance when operated in a recursive mode. In each case the performance characteristics are discussed.
