Abstract: An embodiment of a method and device for detecting a signal and generating bit soft-output of a multiple-input multiple-output system is provided.
The device includes at least one channel estimates pre-processing unit, one received vector processing and one detection and soft-output generation unit.
The pre-processing unit calculates multiple QR Decompositions of the input channel estimation matrix.
The detection and soft-output generation unit computes near optimal bit soft output information with a deterministic complexity and latency.
It may implement a reduced complexity search method.
Globally, embodiments of the invention may allow achieving low complexity, high data rate, scalability in terms of the dimension of the MIMO system and flexibility versus the supported modulation order, all potentially key factors for most MIMO wireless transmission applications.

Abstract: An embodiment of an arrangement for detecting sequences of digitally modulated symbols from multiple sources. The arrangement identifies a suitable set of candidate values for at least one transmitted sequence of symbols and determines for each candidate value a set of sequences of transmitted symbols. The arrangement estimates at least one further set of sequence of transmitted symbols, calculates a metric for each sequence of transmitted symbols and selects the sequence that maximizes the metric. At the end, a-posteriori bit soft output information for the selected sequence is calculated from the metrics for said sequences. Generally, these calculations are base on the information coming from a channel state information matrix and a-priori information on said modulated symbols from a second module, such as a forward error correction code decoder.
