N2 - Reliable communication under interferences is desired by both military and commercial parties. This paper proposes a vertical-Bell Laboratories Layered Space-Time (V-BLAST) architecture with non-stationary interference avoidance capability. A transform domain processing (TDP) and minimum mean square error (MMSE) detector are combined with the V-BLAST to enhance performance in a narrow band interference (NBI) environment. A key idea of TDP is to generate an adaptive modulated information-bearing signal avoiding spectrally crowded regions in the transform domain at both transmitters and receivers of the V-BLAST system. The adaptive interference-free signal is synthesized by a non-parametric spectral estimator, called Capon's method (CM). The proposed V-BLAST system also incorporates the MMSE detector. These approaches offer better bit error performance than other interference mitigation methodologies that process signals at the receiver only, and better than other similar systems that use a parametric spectral estimator with zero-forcing detector. Our simulation results indicate that the proposed system mitigates not only stationary interferences but also non-stationary interferences. Therefore, the proposed system is a viable option for the highly reliable multiple-input multiple-output (MIMO) system. ©2008 IEEE.
