Patent ID: 8036325

Claim:
A method of cancelling interference from received signals, the method comprising: performing successive interference cancellation (SIC) on the received signals to generate SIC signals; determining whether it is desirable to perform interference cancellation using principle component analysis (PCA) on the SIC signals; performing interference cancellation using PCA on the SIC signals to generate PCA signals if it is determined that interference cancellation using the PCA is desirable; determining whether it is desirable to perform interference cancellation using independent component analysis (ICA) on the PCA signals; performing interference cancellation using ICA on the PCA signals to generate ICA signals if it is determined to be desirable to perform interference cancellation using ICA; and demodulating interference cancelled signals, wherein the determination to perform interference cancellation using PCA and the determination to perform interference cancellation using ICA are made based on a demodulated signal and an interference-cancelled signal in a previous processing.
