Abstract
Symbol timing is performed by providing a histogram of samples of a signal for a predetermined number of symbol times. An average, weighted average, or other method is applied to determine an average timing for a max eye opening for each symbol time. The average max eye opening timing is applied to an edge detection of a currently received signal to determine timing of a sample that is most likely to occur closest to the max eye opening for the current symbol. The invention may also be practiced based on a center timing of each symbol.
