Patent ID: 8498252

Claim:
A method, comprising: for a first subband, allocating a number of antennas for transmitting midamble tones to a first group of subcarriers for a sector; repeatedly executing said allocating to a next group of subcarriers for the sector until an end of the subcarriers in a subband is reached; rotating an order of the antennas for transmitting the midamble tones to a different grouping arrangement, wherein the antennas are allocated to subcarriers according to a reuse-3 arrangement or a reuse-1 arrangement; repeating said allocating and said repeatedly executing for one or more additional subbands; and modulating one or more of the subcarriers with a Golay sequence that results in a relatively lower peak-to-average power ratio property and a relatively lower partial cross-correlation for the reuse-3 or reuse-1 arrangement.
