<p>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 taking into account soft values of the first type, (d) performing error correction decoding on the symbol soft outputs, (e) calculating soft values of the second type taking into account error correction decoded outputs , (f) feeding back soft values of the second type, (g) iteratively updating soft values of the first type, symbol outputs, error correction decoded outputs, and soft values of the second type by repeating previous steps, and (h) providing updated error correction decoded outputs.</p> |
