Abstract
It is shown that the sensitivity of the performance of least mean-square error (LMS) equalizers to the sampler phase is a function of equalizer length for partial-response systems. An LMS algorithm for the adjustment of sampler phase is derived for partial-response systems. This algorithm does not require the transmission of any pilot tones and is relatively easily implementable by digital circuits. A method of selecting a "good" initial sampler phase is also proposed.
