ABSTRACT:
Each of a plurality of transmitters (31-37) transmits (62) one of a plurality of known signals. The known signals being known to a receiver (40). The receiver (40) then measures the known signals (63); and using those measurements, estimates the plurality of channel responses (64). The channel responses are then used to determine a power ratio parameter (65) and a phase correction parameter (66).
