Abstract
A signal receiver is configured for receiving signals from multiple antennas, wherein the signal from one of the antennas is phase compensated relative to the signal from another of the antennas. The receiver comprises (i) an equalizer configured to equalize signals received from the antennas in accordance with a determined equalization vector and (ii) a processor for determining the equalization vector. The processor is configured to determine the equalization vector in dependence on (i) a first channel estimate for a first channel from one of the antennas to the receiver and (ii) a phase-adjusted version of a second channel estimate for a second channel from another of the antennas to the receiver.
