| Abstract: | A precoding method utilizing interference is proposed in multiple-input multiple-output broadcasting system(MIMO BC) in which each receiver has one antenna. This method turns a multi-user system into a number of independent two-user or one-user systems.In two-user system a new model based on vector is established,and with the objective of maximizing system capacity the optimal precoding vectors and power allocation are derived.Simulations show that the proposed method has the similar capacity with minimum m... |
