<p>A method for initializing an equalizer in an Orthogonal Frequency Division Multiplexing ("OFDM") receiver includes inhibiting, based at least in part on (a) an equalizer tap being less than a first limit (240) and (b) a time between OFDM signals being less than a second limit (270), an initialization of the tap. In an alternative embodiment, a method includes initializing (260) equalizer taps upon startup, re-initializing (320) the taps upon a passage of a predetermined time between OFDM signals, and selectively re-initializing (300, 340) at least one tap upon divergence of the tap. In another alternative embodiment, an apparatus includes an equalizer (72) and a tap initialization controller (108) coupled thereto. The tap initialization controller (108) is configured to inhibit, based at least in part on (a) a tap being less than a first limit (240) and (b) a time between OFDM signals being less than a second limit (270), an initialization of the tap.</p> |
