This paper discusses implementation aspects of arecently proposed fixed-complexity soft-output (FCSO) symboldetector for MIMO systems . A further approximation tothe FCSO detector is proposed which substantially reduces thecomplexity at the cost of a minor performance loss. With theresulting method, it is possible to carry out close-to ML detectionfor MIMO systems with a large number antennas (e.g. 4×4) usinghigher-order modulation schemes (e.g. 64-QAM) at low siliconcost in real-time. Furthermore, the parallelism inherited by theFCSO algorithm allows massive parallel processing which makesthe method suitable for implementation in multi-core basebandsignal processing hardware architectures.
