Abstract
A method for facilitating an equalization of a simulcast signal comprising: (a) receiving a simulcast signal comprising known data simulcast from at least two different sites; (b) generating a number of simulated simulcast signals, each simulated simulcast signal being based on at least two sites transmitting said known data with a presumed time delay, each simulated simulcast signal having a different presumed time delay; (c) determining which of said simulated simulcast signals is an optimum simulated simulcast signal that correlates most closely to said simulcast signal; and (d) providing time delay data of said optimum simulated simulcast signal for use in equalization of said simulcast signal.

A method for equalizing a simulcast pilot signal at a mobile wireless communications device comprising:
- receiving, at the mobile wireless communications device, the simulcast pilot signal from a plurality of wireless base stations at different locations;
- generating, at the mobile wireless communications device, a plurality of simulated pilot signals, each simulated pilot signal being based on a corresponding time delay;
- determining, at the mobile wireless communications device, a closest match simulated pilot signal from the plurality of simulated pilot signals for the received simulcast pilot signal;
- and
- equalizing, at the mobile wireless communications device, the received simulcast pilot signal using a respective time delay of the closest match simulated pilot signal.
