Patent ID: 8045610

Claim:
A method of controlling a decision feedback equalizer having a feedback filter and K feed forward filter branches, wherein each of the K feed forward filter branches receives an input signal from a corresponding one of a plurality of channels associated with a corresponding one of a plurality of antennas, wherein K>1, wherein each of the K feed forward filter branches provides an output, the method comprising: determining an instantaneous SNR level γ k for each of the K feed forward filter branches; comparing the instantaneous SNR level γ k for each of the K feed forward filter branches to a double threshold, said double threshold including an upper threshold T H and a lower threshold T L ; and, selectively adding the outputs from the K feed forward filter branches dependent upon the comparing of the instantaneous SNR level γ k for each of the K feed forward filter branches to the upper threshold T H and to the lower threshold T L .
