Abstract:
1. A signal receiver for receiving signals from multiple antennas of a transmitter operable to transmit signals from one of its antennas phase compensated relative to signals from another of its antennas, the receiver comprising: an equalizer configured to equalize signals received from the antennas of a transmitter in accordance with a determined equalization vector; and a processor for determining the equalization vector, the processor being configured to determine the equalization vector in dependence on (i) a first channel estimate for a first channel from a first antenna of that transmitter to the receiver, (ii) a phase-adjusted version of a second channel estimate for a second channel from a second antenna of that transmitter to the receiver, the phase-adjusted second channel estimate being determined by means of a received value of phase compensation reported by the transmitter, (iii) a non-phase-compensated signal estimate, and (iv) a phase-compensated signal estimate.
