Apparatus and methods are provided for accounting for the effects of automatic gain control (AGC) in a multi carrier communications system when combining pilot tone interlaces by essentially reversing the effects of the AGC. In an aspect, a method for adjusting for the effects of automatic gain control when combining pilot interlaces in an interlace filter of a communication system is disclosed. The method includes determining a normalization gain of an applied automatic gain control normalized to a predefined time (604). Additionally, two or more combining coefficients for an interlace filter are determined based on a selected criterion (606). Each of the two or more combining coefficients is then modified based on the determined normalization gain (608) to yield adjusted combining coefficients. Corresponding apparatus are also disclosed. |
