ABSTRACT:
A system comprises a correlation module that receives modulated signals from R antennas, that correlates each of the modulated signals with Y preamble sequences, and that generates Y correlation values for each of the R antennas, where R and Y are integers greater than or equal to 1. A control module generates correlation sums by adding each of the Y correlation values for one of the R antennas to corresponding ones of the Y correlation values for others of the R antennas, that selects a largest correlation sum from the correlation sums, and that detects one of the preamble sequences in the modulated signals when a magnitude of the largest correlation sum is greater than or equal to a first predetermined threshold.
