Patent ID: 7289583

Claim:
A method for improving co-channel interference (CCI) and adjacent channel interference (ACI) performance in a receiver, the method comprising: performing synchronization and whitening of the received signal, the synchronization and whitening comprising performing the following steps at least one time: performing a synchronization and vector-noise-correlation estimation of an input signal to yield an interference model; performing a spatio-temporal whitening operation using the interference model and the input signal to yield an updated received signal wherein the spatio-temporal whitening operation is terminated in response to a determination that an energy reduction of a synchronization residue is not sufficiently large; wherein the input signal is the received signal when the step of performing the synchronization and vector-noise-correlation estimation is performed a first time of the at least one time; and wherein the input signal is the updated received signal when the step of performing the synchronization and vector-noise-correlation estimation is performed following the first time of the at least one time; and determining a channel estimate using the updated received signal.
