Pre-equaliser cancellation of sinusoidal phase jitter

Abstract

A new data receiver structure is proposed which removes sinusoidal phase jitters (SPJ) present on the received signals prior to their equalisation. It is shown that under the conditions that the SPJ is excessive, the proposed scheme improves receiver performance significantly when compared with the conventional methods which cancel the SPJ after equalisation of the received signal. This improvement is achieved at the cost of doubling the complexity of the receiver.
