摘要
A technique for wireless signal processing performed at a receiver in a wireless network includes receiving, by a wireless receiver, an orthogonal frequency division multiplexing (OFDM) signal on a shared downlink channel from the wireless network, wherein the OFDM signal includes contribution from a serving cell signal and at least one interfering signal, obtaining an estimate of the serving cell signal, calculating a residual signal by subtracting the estimate of the serving cell signal from the OFDM signal, generating a whitened residual signal by whitening the residual signal, obtaining an estimate of a modulation scheme of the at least one interfering signal by performing a likelihood-based blind classification on the whitened residual signal, and performing further receiver-side processing of the serving cell signal using the estimate of the modulation scheme of the at least one interfering signal.
