Patent ID: 7616557

Claim:
An apparatus for receiving information in a multicarrier communication system, comprising: a demultiplex receiver module, for receiving and demultiplexing a signal having a multiplexed first signal x k and a second signal x′ k , the first signal x k having an orthogonal frequency division multiplexed (OFDM) data stream d n and the second signal x′ k having a conjugate of the first signal x k to produce a first received first signal r k and a received second signal r′ k ; a signal conjugator, coupled to the demultiplexer module, for generating a conjugate of the received second signal (r′ k )*; and a conjugate cancellation orthogonal frequency division multiplexed (CCOFDM) demultiplexer, for generating the information from the received first signal r k and the conjugate of the received second signal (r′ k )* wherein the demultiplex receiver module comprises first downconverter for downconverting the signal to produce the received first signal r k and a second downconverter for downconverting the signal to produce the received second signal r′ k ; wherein the CCOFDM demultiplexer comprises: a combiner, for combining the received first signal r k and the conjugate of the received second signal (r′ k )*; and a Fourier transformer, coupled to the combiner, for Fourier transforming the combined received first signal r k and the conjugate of the received second signal (r′ k )* and for generating the information from a subset of the Fourier transformed combined received first signal r k and the conjugate of the received second signal (r′ k )*.
