Learned Preconditioned Conjugate Gradient Descent for Massive MIMO Detection

Abstract: In this paper, we investigate the use of model-based neural networks for Massive Multiple-Input Multiple-Output (MMIMO) detection. Recently, a new M-MIMO detection architecture called LcgNet ...

A Jacobi-based Conjugate Gradient Solver for Sparse Linear Systems on Multi-GPUs

Abstract: The Preconditioned Conjugate Gradient (PCG) algorithm is a widely-used iterative method for solving sparse linear systems. The sparse matrix-vector multiplication (SpMV) operation involved ...
