1. A method of receiving a wireless communication from first and second space diverse antennas, the wireless communication being further one of time diverse or frequency diverse, the method comprising the steps ofestimating characteristics of a transmit channel over which signals are received from said space diverse antennas and outputting said estimated characteristics to a signal combiner and a maximum likelihood detector, the characteristics being related to a time difference between sequential transmissions from said space diverse antennas;

  • combining said signals received from said first and second space diverse antennas and outputting said combined signals to said maximum likelihood detector as two output data signals responsive to said estimated channel characteristics;

    and detecting respective transmitted signals in the presence of noise via said maximum likelihood detector responsive to said estimated channel characteristics.
