METHOD FOR ITERATIVE ESTIMATION AND DECODING OF CHANNELS AND INTERFERENCES Russian patent published in 2008 - IPC H04L1/02 H04J13/06 H03M13/00 

Abstract RU 2322762 C1

FIELD: communications engineering.

SUBSTANCE: according to the plan for iterative estimation of channel and interferences and decoding, firstly, a priori information is received about channel amplification and interference on basis of received symbols of pilot-signal, anticipatory information for code bits, which correspond to received symbols of data, is outputted on basis of received symbols of data and a priori information and then decoded to produce check connection information for code bits, which correspond to received symbols of data, on basis of check connection information for these received data symbols. A posteriori information is received for amplification of channel and interferences for each received symbol of data, a posteriori information for received symbols of data and a priori information are combined to produce updated information for amplification of channel and interferences for each received symbol of data.

EFFECT: production of updated information for amplification of channel and interference, and also estimation of channel phase in a wireless communications system.
