Maximum likelihood detection

摘要

A method of symbol detection in an electronic device employing multi-user multiple input multiple output (MU-MIMO) communication over a first transmission layer of first and second transmission layers comprises various steps. A receiver comprises processing circuitry for performing these steps. A transmitted signal is received. The transmitted signal is decoded by detecting data symbols within the transmitted signal for the first transmission layer by performing Maximum Likelihood (ML) detection on the first transmission layer. ML detection comprises performing a search across all possible symbol constellation points in a set of constellation points available for the second transmission layer.

1. A method of symbol detection in an electronic device employing multi-user multiple input multiple output (MU-MIMO) communication over a first transmission layer of first and second transmission layers, comprising:
receiving a transmitted signal; and decoding the transmitted signal by detecting data symbols within the transmitted signal for the first transmission layer by performing Maximum Likelihood (ML) detection on the first transmission layer, wherein the step of performing ML detection comprises performing a search across all possible symbol constellation points in a set of all constellation points available for the second transmission layer and wherein said set of symbol constellation points for the second transmission layer comprises a zero point and all points in QPSK, QAM16 and QAM64 modulation schemes.
