Fast recursive algorithm for implementation of MIMO ZF-SIC detection
Published 2012-07-01“…To reduce the complexity of the zero-forcing(ZF)detection with successive interference cancellation(SIC)in a Vertical Bell Labs layered space-time(V-BLAST)systems,a computationally efficient recursive algorithm was proposed.A fast implementation of the proposed algorithm was developed and its complexity was analyzed in detail.Theoretical analysis and simulations demonstrate significant advantages of the proposed algorithm over the fast recursive algorithm (FRA)on complexity,practicability and storage requirements.Moreover,its performance on symbol error rate(SER)is close to optimal under practical conditions.These advantages make the proposed algorithm more efficient and practical.…”

GC–MS/MS–based multiresidue pesticide analysis in mealworm (Tenebrio molitor) larvae: Optimization of standard QuEChERS-based method to minimize matrix effects
Published 2025-04-01“…Given the unsuitability of the standard quick, easy, cheap, effective, rugged, and safe (QuEChERS)-based method for multiresidue pesticide analysis in mealworm larvae due to their complex composition and high lipid content, we established a gas chromatography-tandem mass spectrometry–based procedure for the detection and quantitation of 247 pesticides in this matrix. The optimized extraction solvent (0.1 % formic acid in acetonitrile) was combined with the original QuEChERS salt packet to achieve high recovery rates, and matrix-derived interferents were effectively removed without analyte loss using primary secondary amine–based dispersive solid-phase extraction (cleanup step). …”
