Abstract :
A model of MIMO broadcast channel for multicell is proposed. We proposed a new method to evaluate the sum rate capacity of the MIMO BC of multicell system. We transformed it into a standard convex optimization problem to get an upper bound of sum rate. By suboptimal modified greedy power allocation algorithm we get a lower bound with the constraint of power. Simulation shows that these two bounds are comparative compact at high SNR.
