Uniformly oversampled sequence detection in the presence of unknown jitter

In this paper we propose a technique to deal with unknown random jitter in a band-limited Gaussian channel. The jitter caused by the deviation or displacement of signal pulses affects the performance of the communication system. We show that a sampling set as small as twice the baud rate is enough for good detection performance. Detection is done by means of a suboptimal algorithm with polynomial time computational complexity. The results are compared for different transmission rates. The simulation results for Gaussian pulses and sinc pulses show that despite the sub-optimality of our algorithm, the bit-error probability remains relatively close to optimum.
