A method for initializing an equalizer in an Orthogonal Frequency Division Multiplexing
("OFDM") receiver includes generating a desired equalizer tap setting based on
an adaptive algorithm. An initial setting for the adaptive algorithm corresponds
to an approximate inverse of a channel estimate, and the desired tap setting corresponds
to an ideal inverse of the channel estimate. In an alternative embodiment, a method
includes generating a channel estimate, generating an equalizer tap setting based
on a complex conjugate of the estimate and a quantized magnitude squared of the
estimate, and repeatedly generating subsequent tap settings until an error falls
within limits. In another alternative embodiment, an apparatus includes a tap initialization
controller configured to: generate a channel estimate, generate an equalizer tap
setting based on a complex conjugate of the estimate and a quantized magnitude
squared of the estimate, and repeatedly generate subsequent tap settings until
an error falls within limits.
