摘要： In the implementation of timing recovery in conventional communication systems, significant errors are generated from modulo operations under certain extreme conditions by taking input signals of a slicer as datum points. In order to prevent such errors, the input signal of a modulo processing circuit is taken as the datum point in place of the input signal of a slicer. This technique could also be applied to communication systems adopting the minimum mean-square error algorithm, the zero-forcing algorithm, or other relevant algorithms.
