L1-norm transformation in soft-output MIMO detector

摘要

A method of processing a signal within a receiver can include generating, using the receiver, a candidate list including at least one entry for a signal. Each entry can include a candidate symbol vector and an L1-Norm error metric. The method can include, for each entry, generating an L1-Norm transformation from the L1-Norm error metric, wherein the L1-Norm transformation depends upon a function of a number of receiving antennas of the receiver. The signal can be decoded using the candidate list including the L1-Norm transformations.
