Abstract
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 on the Barker correlated signal to generate an autocorrelated signal. The autocorrelated signals from the multiple chains can be summed to generate a summed output. Additional processing, e.g. at least one of CCK weak signal detection, peak selection in a rake receiver, frequency estimation, and differential decoding, can then be performed based on the summed output.
