Low-Complexity Lattice Reduction-Aided Regularized Block Diagonalization for MU-MIMO Systems

Abstract

By employing the regularized block diagonalization (RBD) preprocessing technique, the MU-MIMO broadcast channel is decomposed into multiple parallel independent SU-MIMO channels and achieves the maximum diversity order at high data rates. The computational complexity of RBD, however, is relatively high due to two singular value decomposition (SVD… (More)
