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; determining a spatial weighting vector using 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.
