A method and apparatus for detecting a plurality of data streams in a signal received via a plurality of radio channels of a mobile communication system, wherein mean and variance of transmitted symbols of the data streams are calculated from an extrinsic soft information output of a soft input soft output decoder. The variance is used to calculate an adjoint matrix and determinant of the matrix for detecting each of the plurality of data streams in an iterative way based on a channel estimation of the plurality of radio channels. The mean and the channel estimation output are used for iterative interference cancellation for each data stream of the received signal. A data stream of the plurality of data streams is then estimated by applying minimum mean square error, MMSE, detection to the interference-cancelled signal for the data stream. |
