A system that facilitates obtaining a coarse estimation of a boundary of symbol with respect to time comprises a peak detector that detects a peak energy of an energy distribution output by a correlator, and an estimating component that adaptively estimates a boundary of the symbol based as a function of the detected peak energy. A parameter defined as a function of the magnitude to create a threshold value, the estimate obtained as a function of a comparison of the threshold with the energy distribution.
