Abstract:
1. A method for setting timing of sampling of one or more symbols comprising: determining by a transceiver an energy density profile of effective interference occurring in at least symbol based on static intersymbol interference and dynamic effective interference; determining an estimated channel energy profile of the at least one symbol based on the magnitude of the gain at one or more samples; calculating a composite channel energy profile of at the least one symbol based on the estimated channel energy profile and including a summation of a short term channel energy profile and a long term channel energy profile accounting for channel fading; determining a total effective interference energy profile by multiplying the energy density profile and the composite channel energy profile for one or more samples; determining a minimum of the calculated total effective interference energy profile over a predetermined sampling period; and setting a start of timing of the symbol for a subsequent sampling period based on the calculated minimum of the total intersymbol interference energy profile.
