Patent ID: 7912142

Claim:
An apparatus for reducing a carrier-to-noise ratio (C/N) in an orthogonal frequency division multiplexing (OFDM) receiver using diversity combining techniques in the presence of inter-carrier-interference (ICI), said apparatus comprising: an encoded data estimator that estimates data received in said OFDM receiver; a pair of ICI estimators operatively connected to said encoded data estimator, wherein said pair of ICI estimators calculate an inter-carrier-interference term of said data; a pair of diversity combining equalizers that compensate multi-path interference of said data, wherein a first one of said diversity combining equalizers is operatively connected to said encoded data estimator, and a second one of said diversity combining equalizers is operatively connected to said pair of ICI estimators; and at least one processor operatively connected to said OFDM receiver, wherein said at least one processor processes said data.
