1. An electronic circuit for receiving a wireless communication from first and second space diverse antennas, the wireless communication being further one of time diverse or frequency diverse, the electronic circuit comprising:

  • a channel estimator for generating estimated transmit channel characteristics of transmit channels over which the communication from the first and second space diverse antennas are communicated to the electronic circuit and outputting said estimated transmit channel characteristics to a signal combiner and to a detector;

    said signal combiner for combining signals received from said first and second space diverse antennas and outputting combined signals to said detector as two output data signals responsive to said estimated transmit channel characteristics; and

    said detector for detecting respective transmitted signals in the presence of noise responsive to said estimated transmit channel characteristics and in accordance with a decision rule.
