Summary: 
In this letter, we reduce the computational complexity of the conventional iterative MMSE-ML signal detection method for multiple input multiple output (MIMO) single carrier FDMA (SC-FDMA) systems, without compromising the error performance. Complexity analysis confirms the efficacy of the proposed modification.
