Abstract — Regularized block diagonalization (RBD) is a new linear precoding technique for the multi-antenna broadcast channel and has a significantly improved sum rate and dive...
— Recently a number of transmission schemes have been introduced to achieve sum capacity for multiuser multiinput multi-output (MIMO) broadcast channels (BC). A block diagonaliza...
