Quantum evolutionary complex sphere decoder algorithm (QECSDA) is proposed. A brief analysis is then given to the theoretical basis and practical performance of signal detection in multiple-input multiple-output communication systems using QECSDA. The emulation results have shown that the proposed algorithm outperforms not only the zero-forcing (ZF) detector but also the ordered successive cancellation (OSIC) detector in both a symmetrical system and an asymmetrical system.
