1. A method comprising:

  • receiving a burst having a known training sequence at a set of diversity antennas;

    sampling the received burst at each antenna;

    determining a coarse timing estimate for samples from at least one antenna;

    calculating a spatial weighting vector using values computed in determining the coarse timing estimate;

    applying the spatial weighting vector to the received burst samples for each antenna to form a single channel signal;

    determining a fine timing estimate for the single channel signal;

    determining a second spatial weighting vector using the fine timing estimate;

    applying the second spatial weighting vector to the received burst samples for each antenna to form a second single channel signal; and

    demodulating the second single channel signal.
