Patent ID: 7184500

Claim:
A system for combining signals comprising: a plurality of antennas operable to receive a plurality of groups of signals at a mobile device, each group of signals comprising a plurality of signals, each signal having a time slot, at least two of the antennas separated by a distance within a range of 0.1 to 1.0 wavelength; an estimator operable to establish a signal quality associated with each time slot of each signal of the groups of signals; a signal adjustment module operable to repeat the following for each group of signals of the plurality of groups of signals: set a current group character associated with a current group of signals; set an adjustment associated with a time slot of each signal of the current group of signals, the adjustment comprising an adjustment of a relative phase distribution among the signals or an adjustment of a relative power distribution among the signals; adjust each signal of the current group of signals at the time slot in accordance with the adjustment associated with the time slot; receive the signal-to-noise ratio associated with each time slot of each signal of the current group of signals; determine an optimal adjustment in accordance with the received signal qualities; set the adjustment for the next group of signals to the optimal adjustment; and a vector modulator operable to: combine the plurality of signals of each group of signals to form one or more combined signals, the number of the combined signals being less than the number of the plurality of signals of the group of signals received at the plurality of antennas; and calibrate the optimal adjustment in accordance with a look-up table entry, the look-up table entry associated with a deemphasis of a non-constant signal characteristic.
