A Supernodal Out-of-Core Sparse Gaussian-Elimination Method
Abstract. We present an out-of-core sparse direct solver for unsymmetric linear systems. The solver factors the coefficient matrix A into A = PLU using Gaussian elimination with pa...

Adaptive Precoding for Switching between Spatial Multiplexing and Diversity in MIMO OFDM with Transmit Antenna and Path Correlat
Abstract— The path and antenna correlations significantly degrade the system capacity in spatially-multiplexed multiple-input multiple-output (MIMO) orthogonal frequency-divisio...
