METHOD FOR ITERATIVE DETECTION AND DECODING OF SIGNAL IN COMMUNICATION SYSTEMS WITH MIMO CHANNEL Russian patent published in 2014 - IPC H04L27/04 

FIELD: radio engineering, communication.

SUBSTANCE: method for iterative detection and decoding of a signal in communication systems with a MIMO channel includes two steps: at the first step, generating a Minimum Mean Square Error (MMSE) estimate of a transmitted symbol using a linear MMSE filter; at the second step, via linear transformation of each n-th (where n=1, 2, (N)) component $${\tilde{x}}_{MMSE,n}$$ of the vector of MMSE estimates $${\tilde{X}}_{MMSE}$$ and the corresponding a priori mathematical expectation, performing correction and finding a new linear estimate $${\tilde{x}}_{LMS,n}$$ of the transmitted QAM symbol and error variance for said estimate $${\sigma }_{{}_{\text{LMS}\text{,n}}}^{\text{2}}.$$

EFFECT: high efficiency and quality of data transmission.
