Hybrid-QRD-SIC and imbalanced MCS system and method for MIMO

A computer program product encoded on a non-transitory medium, the product comprising computer readable instructions for causing one or more processors to perform operations comprising:

• decomposing a channel complex gain matrix into a unitary matrix and an upper right hand triangular matrix;
• providing a received signal to a complex conjugate transpose of the unitary matrix, thereby creating a plurality of signals;
• normalizing a last of the plurality of signals;
• channel decoding the normalized last of the plurality of signals, thereby recovering a last codeword signal;
• encoding the last codeword signal;
• utilizing the encoded last codeword signal to recover a second last codeword signal;
• and repeating the utilizing until all codeword signals are recovered.
