The capacity gain of mobile multimedia broadcasting system by using CSIT in MIMO

Many researches prove that MIMO can enlarge the channel capacity without extra bandwidth and transmission power. This paper uses the MIMO technology in mobile multimedia system, describes the increasing of the channel capacity. Then, this paper describes the application of CSIT and calculates the capacity gain caused by it. At last, the benefit of the CSIT is proved by computer simulations on the base of DAB/DMB standard.
