1. A computer-implemented reconstruction method of discrete digital signals in noisy overloaded wireless communication systems that is characterized by a channel matrix of complex coefficients, the method including
Receiving the signal from channel by a signal detector;
Measuring the noise power by a noise power estimator at the receiver;
Forwarding the detected signal and noise power estimation to a decoder that estimates the transmitted symbol-(s),
wherein the estimation of the decoder produces a symbol that could have been transmitted and that is forwarded to a de-mapper, which outputs the bit estimates corresponding to the estimated transmit signal and the corresponding estimated symbol to a microprocessor for further processing; and
wherein the decoder uses the noise power estimation explicitly within the decoding process in such a way that it minimizes the effect of noise amplification.
