Abstract :
A computationally efficient V-BLAST detection scheme on Rayleigh flat-fading channels is proposed. The proposed scheme provides a near-ML performance with significantly reduced complexity as compared to other well-known detection techniques. Moreover, the reduced complexity is independent of signal-to-noise ratio, which is a big practical advantage.
