Abstract
The present invention provides a gain training generator for use with a multiple-input, multiple-output (MIMO) transmitter employing N transmit antennas where N is at least two. In one embodiment, the gain training generator includes a fundamental training encoder configured to provide a basic gain training sequence to one of the N transmit antennas during a time interval to produce a basic gain training waveform having a basic peak-to-average ratio (PAR). Additionally, the gain training generator also includes a supplemental training encoder coupled to the fundamental training encoder and configured to further provide (N−1) supplemental gain training sequences to (N−1) remaining transmit antennas, respectively, during the time interval to produce supplemental gain training waveforms wherein each has a supplemental PAR substantially equal to the basic PAR.
