Methods, apparatuses, and systems are presented for deriving data from an error correction encoded composite signal involving (a) receiving a composite signal comprising contributions from a plurality of individual signals transmitted over different paths representing a common data sequence encoded using an error correction code, (b) calculating soft values of a first type taking into account the received composite signal and soft values of a second type, (c) generating symbol outputs by taking into account soft values of the first type, (d) calculating soft values of the second type taking into account symbol outputs, (e) feeding back soft values of the second type, (f) iteratively updating soft values of the first type, symbol outputs, and soft values of the second type by repeating previous steps, and (g) performing error correction decoding taking into account updated symbol outputs, to generate error correction decoded outputs.
