Claim One:
1. An iterative detection and decoding method in a Multiple Input Multiple Output (MIMO) system, comprising the steps of: generating soft decision values by performing a detection of an entire set of MIMO nodes; decoding a first decoding station using the generated soft decision values to produce a first decoding value; re-generating soft decision values by performing a redetection of a first MIMO node, from the set of MIMO nodes, that corresponds to the first decoding station, when a variation between the first decoding value and a corresponding one of the generated soft decision values is greater than a reference value; decoding a second decoding station using at least one of the generated soft decision values and the re-generated soft decision values to produce a second decoding value; and re-generating soft decision values by performing a redetection of a second MIMO node, from the set of MIMO nodes, that corresponds to the second decoding station, when a variation between the second decoding value and a corresponding one of the generated soft decision values is greater than the reference value; wherein the decoding step and the re-generating step are performed a number of times equal to a total number of decoding stations and the number of decoding and regenerating steps are iterated at least one time.
