Patent ID: 8050335

Claim:
A method, comprising: receiving and synchronizing, via a symbol synchronizer module of a receiver, a transmitted data packet comprising orthogonal frequency division multiplexing (OFDM) symbols having cyclic prefixes; removing, via a cyclic prefix remover module, the cyclic prefixes from the OFDM symbols to form time domain symbols; converting, via a fast fourier transform (FFT) module, the time domain symbols to frequency domain symbols consisting of multiple sub-carriers; estimating, via a channel estimator, channel coefficients at the multiple sub-carriers of the frequency domain symbols through at least one known OFDM symbol of the OFDM symbols transmitted at any position of the data packet; equalizing, via an equalizer, the multiple sub-carriers of the frequency domain symbols with complex conjugate of the estimated channel coefficients at respective sub-carrier frequencies; combining, via a combiner, the frequency domain symbols spread over the multiple sub-carriers during transmission upon equalizing the multiple sub-carriers; and detecting, via a detector module, phase information of the combined frequency domain symbols.
