Patent ID: 7395291

Claim:
A method for correlating an input signal with a sequence of alternative correlator coefficients, an alternative sequence associated with a specified non-negative integer n, the method comprising: digitally sampling the input signal to generate a plurality of real signal digital samples and a plurality of imaginary signal digital samples, wherein the input signal is compliant with at least one specification selected from IEEE 802.11a WLANs or HIPERLAN/2; scaling the plurality of real signal digital samples in accordance with a selected sequence of alternative correlator coefficients to generate a plurality of scaled real signal samples; scaling the plurality of imaginary signal digital samples in accordance with the selected sequence of alternative correlator coefficients to generate a plurality of scaled imaginary signal samples; and combining, in accordance with a specified correlator form, a first subset of the plurality of scaled real signal samples and a second subset of the plurality of scaled imaginary signal samples to generate at least one correlator output signal.
