Apparatus and method for iterative detection and decoding in mimo wireless communication system

The present invention in a communication system using multiple antennas of a reception apparatus and method (iterative detection and decoding) IDD. And a MIMO detector for generating a soft decision value of IDD receiving apparatus, the received vector, feedback dictionary information (priori information), a candidate code with the list of symbol vectors to MIMO decoding each code bit (coded bit) that is in accordance with the invention, and decoders for feeding back the soft decision value of each code bit in the MIMO detector decodes the soft decision values ​​generated by the MIMO detector SISO (soft-input / soft-output), appointed hard decision of soft decision values ​​generated by the decoder and the first hard decision unit which generates a code symbol vector, from in the first iteration (iteration) in the generating the list of candidate code symbol vector using the received vector and provided to the MIMO detector, since the repetition of the first hard decision by use of a code symbol vector to update the said list includes list update unit provided in the MIMO detection. This invention has the advantage that by using the additional information is passed from the decoder to a MIMO detector for by updating the list, improve the decoding performance by small number of iterations. MIMO, IDD, the list update, additional information,
