A novel oblique projection based detection scheme is proposed to reduce the computational cost of the vertical Bell Laboratories Layered Space-Time (V-BLAST) receivers. It constructs the ordinary zero-forcing (ZF) and minimum mean-square error (MMSE) detectors by oblique projector implementation, and has a computationally efficient way via projection matrix recursion. Different from the existing ones, we design a so-called "inverse" detection order to facilitate this new approach, whose complexity compares favorably with the competing alternatives. Theoretical analysis and simulation results show the efficiency of the proposed algorithm.
