Abstract:
A system including a control module and a correlation module. The control module partitions a total number of subcarriers, in a received signal, into a predetermined number of bands. The correlation module generates a plurality of correlation values for a plurality of preamble sequences. A correlation value for a preamble sequence is generated by correlating symbols in each band with corresponding symbols in the preamble sequence to generate correlations for each band, adding the correlations generated for a respective band to generate a sum for each band, and adding the sums generated for all the bands. The control module select a largest correlation value from the plurality of correlation values and determine that one of the preamble sequences is detected in the received signal in response to the largest correlation value being greater than or equal to a predetermined threshold.
