Abstract

Techniques for increased pilot detection accuracy are disclosed, which provide the benefits of increased acquisition speed, increased data rate, decreased power, and improved overall system capacity. In one aspect, pilot energy calculations corresponding to PN offsets surrounding the PN offset of a local pilot energy maximum are combined with that local pilot energy maximum resulting in a compensated, more accurate local pilot energy maximum. In another aspect, the combination of nearby energy calculations is combined with the local pilot energy maximum via a function with pre-calculated compensation factors. The pre-calculated compensation factors can be determined to minimize mean-squared error in the resultant compensated local pilot energy maximum. These factors can be calculated based on a matched filter. The techniques described herein apply equally to both access points and access terminals.
