Abstract
The present invention provides a time-switched preamble supplement generator for use with a multiple-input, multiple-output (MIMO) transmitter employing N transmit antennas wherein N is at least two. In one embodiment, the time-switched preamble supplement generator includes an initial preamble supplement formatter configured to provide a first permutation of a set of preamble supplements to the N transmit antennas during an initial time interval. The first permutation includes a single first preamble supplement and at least one second preamble supplement. The time-switched preamble supplement generator also includes a subsequent preamble supplement formatter coupled to the initial preamble supplement formatter and configured to provide (N−1) mutually exclusive further permutations of the set to the N transmit antennas during (N−1) subsequent time intervals.
