Abstract
An antenna selector selects one antenna during an interval of control signal. A receiving weight vector computing unit computes receiving weight vectors. During an interval of data signal, a multiplier in a signal processing unit weights digital received signals with the receiving weight vectors so as to output composite signals. During an interval of control signal, a switch selects an output signal from the antenna selector as an output signal from a signal processing unit whereas during the interval of data signal it selects the composite signal. A carrier control unit outputs carrier recovered by a carrier recovery unit. A multiplier in a modem unit multiplies signal-processing-output-unit signals by signals from the carrier control unit.
