Abstract

A system and method for data detection in a wireless communication system wherein the system comprises a receiver for receiving spatial-­subspace data transmitted over a plurality of spatial-subspace channels of a sub-carrier which may comprise at least one of coded and uncoded spatial-­subspace channels. The receiver comprises a receiver weighting unit for providing receive-weighted spatial-subspace data and a data estimation unit for performing an iterative processing method on the receive-weighted spatial-subspace data to estimate output data related to the input data symbol stream. The iterative processing method comprises successively processing data on each of the plurality of spatial-subspace channels in the receive-weighted spatial-subspace data.
