Abstract:
1. An orthogonal frequency-division multiplexing (OFDM) receiver system comprising: a plurality of antennas configured to receive a plurality of modulated signals, wherein each antenna is configured to receive a corresponding modulated signal; a plurality of autocorrelators configured to generate a plurality of autocorrelated signals by autocorrelating the plurality of modulated signals received by the plurality of antennas; a first module configured to determine whether a signal strength associated with each modulated signal received by the plurality of antennas is (i) below a threshold or (ii) above the threshold; a second module configured to a third module configured to generate weighted autocorrelated signals based on (i) the plurality of autocorrelated signals and (ii) the modulated signals combined by the second module; a fourth module configured to generate a combined weighted signal by summing the weighted autocorrelation signals; and a fifth module configured to demodulate the combined weighted signal generated by the fourth module.
