Abstract

Systems, devices, and methods related to selecting a sample phase of a signal are disclosed. A method includes sampling a signal including a plurality of symbols with a plurality of different sample phases to obtain sample values of each of the plurality of symbols at each of the plurality of different sample phases. The signal is received from a shared transmission medium. The method also includes determining an edge sample phase of the plurality of different sample phases that corresponds to edges of the symbols based on the sample values. The method further includes determining a center sample phase of the plurality of different sample phases based on the determined edge sample phase, and using the determined center sample phase to determine values of the symbols.
