摘要
In an embodiment of an equalizer, a demodulator for MMSE-SIC receives a symbol vector to provide first information. A decoder receives the first information to provide second information to the demodulator. The decoder iteratively processes the first information to provide the second information. The demodulator and decoder are coupled in a loop for feeding back the second information for iteratively refining the first information. A detection-cancellation block of the demodulator receives the symbol vector to provide an equalized vector. A channel pre-processor block of the demodulator receives an initial vector output of the detection-cancellation block for the symbol vector for a demodulating-decoding iterative sequence to provide a weight vector. The channel pre-processor block provides an approximation using a fixed matrix to generate the weight vector. The detection-cancellation block receives the weight vector for equalization of the symbol vector in order to provide the equalized vector.
