摘要：A pseudo-noise (PN) correlation and demodulation method and apparatus, inwhich received signals are correlated with locally generated PN codes and correlationmeasurements are maintained for multiple time bins corresponding to signals receivedover possible multiple paths. Instead of selecting one or a small number of significantcorrelation measurements to control data demodulation, the method of the inventionperforms data demodulation over the multiple time bins, and then selects data valuescorresponding to significant correlation measurements and combines the selected datavalues, weighting them in accordance with their relative strengths a determined duringcorrelation. Use of the invention provides improved performance in terms of signalquality and continuity in the presence of multipath conditions. Careful selection of designparameters allows the improved performance to be obtained in a compact and easilyportable implementation including transmitter and receiver modules.
