ABSTRACT:
A receiver includes a demodulator that receives data packets each having a preamble and that generates spreading codewords by correlating a spreading code with the preambles of the data packets. A signal quality device determines signal quality values at a plurality of antennas for each of the data packets after correlation with corresponding ones of the spreading codes and selects one of the plurality of antennas based on the signal quality values. Each of the signal quality values includes a peak-to-average ratio value.
