Patent ID: 7668269

Claim:
A method of signal processing, said method comprising: estimating a plurality of components of a response of a transmission channel during a symbol period; based on said estimated components of a response of the transmission channel, estimating a plurality of components of a model of a phase noise process during the symbol period; and based on said plurality of estimated components of a model of a phase noise process, estimating a plurality of values of a symbol received during the symbol period, wherein each of said plurality of estimated components of a response of a transmission channel corresponds to a different one of a plurality of subcarriers, and wherein each of said plurality of estimated values of a symbol corresponds to a different one of said plurality of subcarriers, and wherein each of said plurality of estimated values of a symbol is based on at least one product of (A) one among said plurality of estimated components of a response of a transmission channel that corresponds to a neighboring one among the plurality of subcarriers and (B) one of said plurality of estimated components of a phase noise process.
