Adaptive beam tracking for interference alignment in time-varying MIMO interference channels: Conjugate gradient approach
Based on a linear formulation to interference alignment, an adaptive algorithm for interference-aligning beam tracking in time-varying MIMO interference channels is proposed. It i...

Updating an LU Factorization with Pivoting
We show how to compute an LU factorization of a matrix when the factors of a leading principle submatrix are already known. The approach incorporates pivoting akin to partial pivo...
