A method including: receiving, through a wireless channel, a plurality of modulated signals at a plurality of antennas, wherein each antenna receives a corresponding modulated signal; generating a plurality of autocorrelated signals by autocorrelating the plurality of modulated signals; determining whether a signal strength associated with each modulated signal is (i) below a threshold or (ii) above the threshold; for each modulated signal having a signal strength below the threshold, disabling the antenna that received the modulated signal having the signal strength below the threshold; combining the modulated signals having a signal strength above the threshold; generating weighted autocorrelated signals based on (i) the plurality of autocorrelated signals and (ii) the combined modulated signals; generating a combined weighted signal by summing the weighted autocorrelation signals; demodulating the combined weighted signal; and determining a state of the wireless channel based on the demodulation of the combined weighted signal.
