1. A computer-implemented reconstruction method of discrete digital signal recovery in noisy overloaded wireless communication systems in the presence of hardware impairments that is characterized by a channel matrix of complex coefficients, the method including
Receiving the signal from channel by a signal detector
Estimation of Hardware Impairments parameter η is done at the receiver
Estimation noise power is done by a noise power estimator
Forwarding the detected signal and hardware impairments parameter η 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 it 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.
