  • System and method for reducing interference in an orthogonal frequency division modulation system
    Patent number: 7876868
    Abstract: An interference contribution associated with a selected subcarrier of a plurality of subcarriers associated with a previously transmitted OFDM symbol or a current OFDM symbol is determined. A fast Fourier transform (FFT) output for the current OFDM symbol is also determined. The interference contribution is subtracted from the FFT output of the current OFDM symbol to form a modified FFT output.

  • SYSTEM AND METHOD FOR DEMODULATING DATA IN AN ORTHOGONAL FREQUENCY DIVISION MODULATION SYSTEM
    Publication number: 20080165673
    Abstract: First incoming data comprising at least one OFDM symbol is received (302). A plurality of timing relationships is determined and each of the plurality of timing relationships relates to an alignment window of a fast Fourier transform (FFT) (304). Each of the plurality of timing relationships is applied to the first incoming data (306) and a plurality of achievable interference metrics associated with the first incoming data is responsively determined (308). Each of the plurality of achievable interference metrics is associated with a selected one of the plurality of timing relationships. The preferred interference metric is chosen from amongst the plurality of achievable interference metrics.
