OSIC (Order Successive Interference Cancellation) is a conventional MIMO detection algorithm for MIMO OFDM in LTE/LTE-A due to its significant performance gain over linear detection algorithm. But, it suffers from error diffusion, leading to performance decrease in low SNR. The tradeoff between complexity and detection performance is not optimal enough. In this paper, we proposed an adaptive MIMO detection approach for the suppression of error diffusion and reduction of complexity in LTE/LTE Advanced System (Uplink) based on the analysis of OSIC and its modification. This approach combines linear and nonlinear algorithm according to real-time SINR and the symbol error rate threshold. Simulation results show that the proposed algorithm suppresses the error diffusion and reduces the complexity successfully with the appropriate threshold.
