Abstract
Methods and apparatus are provided for adapting one or more equalization parameters in a communications system by reducing group delay spread. According to one aspect of the invention, one or more equalization parameters in a communications system are adapted by detecting one or more predefined run length patterns in a received signal, such as a plurality of consecutive same-valued bits; evaluating a transition latch value for each of the detected predefined run length patterns, wherein the transition latch value provides an indication of whether the received signal is under-equalized or over-equalized; and adjusting the one or more equalization parameters of the communications system based on the evaluation of the transition latch value. The adjusted equalization parameters may be employed to equalize intersymbol interference. A data eye monitor can be employed to evaluate the transition latch value.
