A method of processing a signal in a wireless network including multiple chains is provided. This method can include receiving the signal in a receiver and, for each chain, performing a Barker correlation on the signal to generate a Barker correlated signal. At this point, an autocorrelation can be performed...http://www.google.com/patents/US8068562?utm_source=gb-gplus-sharePatent US8068562 - Signal processing for multiple chains including barker code correlation and auto-correlation
