Classification: CPC H  G | IPC G  H

Claim 0:
1. A method for classifying a modulation scheme of a wireless signal, comprising:
receiving a modulated wireless signal;
estimating a center frequency of the wireless signal;
estimating a bandwidth of the wireless signal;
generating a resampled signal from the received modulated wireless signal wherein a rate of the resampled signal is based on the estimated center frequency and the estimated bandwidth of the wireless signal, wherein generating a resampled signal from the wireless signal comprises performing blind equalization in an iterative manner, and wherein during each iteration, the resampled signal is convolved with a plurality of equalization taps and a convolved signal envelope is used to determine whether to adjust a plurality of equalization weights; and
classifying the received wireless signal using a modulation classifier to a modulation scheme based on the resampled signal.
