Abstract
A method and system for decoding signals includes a transmitter configured for transmitting signals encoded with a mapping, with different and separable configurations in a real part and an imaginary part of the signal. The signals may be encoded according to a Gray or QAM mapping, and may be transmitted on a selective MIMO channel and/or multiplexed with an OFDM technique. The corresponding receiver is configured for decoding the real part and the imaginary part of the signals separately, and may include a filter for subjecting the encoded signals to a Wiener filtering and a MMSE detector for minimizing the mean-square error between the encoded signals and the result of the Wiener filtering. The receiver may also include a soft decoder for performing a soft estimation of the signals and cancelling, using the results of the soft estimation, an interference produced on the signals.
