1. A method for signal processing of signals associated with an antenna array;

  • the method comprising;

    converting M and N uplink electromagnetic signals from a phased array and a diversity array, respectively, into uplink baseband signals for digital signal processing, the uplink baseband signals being observable as a series of successive time slots, where M and N are positive integers;

    applying M coarse combining weights to combine the uplink baseband signals associated with the phased array on a time slot by time slot basis;

    summing the weighted M, uplink baseband signals of the phased array into at least one resultant baseband signal; and

    determining fine combining weights for the at least one resultant uplink signal and the N uplink signals to form a single receive channel for subsequent symbol detection, the fine combining weights applying to a duration less than one of the time slots.
