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.
Claims9
A signal receiver for receiving signals from multiple antennas associated with a base station, the signal from one of the antennas being phase compensated relative to the signal from another of the antennas, the receiver comprising:
- an equalizer configured to equalize signals received from the antennas 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 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.
A method for receiving signals from multiple antennas, the signal from one of the antennas being phase compensated relative to the signal from another of the antennas, the method comprising:
- determining an 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;
- and
- equalizing signals received from the antennas in accordance with the determined equalization vector.
