To derive low-complexity multiple-input-multiple-output 4 (MIMO) detectors, we combine two complementary approaches, i.e., lat-5 tice reduction (LR) and list within the framework of the successive interfer-6 ence cancellation (SIC)-based detection. It is shown that the performance 7 of the proposed detector, which is called the SIC-based detector with list 8 and LR, can approach that of the maximum-likelihood (ML) detector with 9 a short list length. For example, the signal-to-noise ratio (SNR)
