Vertical Bell Lab Layered Space-Time is a spatial multiplexing (SM) multi-input multi- output (MIMO) scheme that provides high spectral efficiency with low computational complexity. Ordered Successive Interference Cancellation (OSCI) is known as most representative detection algorithm for SM MIMO system. Error propagation is a major drawback constraining the overall performance of OSIC detection significantly. To solve this problem, we propose a new detection algorithm, which improves the performance of the conventional detection algorithm with reasonable increase of computational complexity. Simulation results show that the proposed algorithm outperforms the conventional detection algorithm under spatially uncorrelated as well as correlated channels.
