Abstract
Systems and methods are provided for performing the required phase calculation in a telecommunications system in order to optimize system performance more quickly and with reduced complexity as compared to prior approaches to solving this problem. In accordance with the preferred exemplary embodiment of the present invention, the phase delay of the precursor EQ is utilized for estimating the entire DFE phase shift by calculating the estimation exclusively based on an output of the precursor EQ this estimation is then used for adjusting the timing phase based on the phase estimation.
