%X The rate-distortion theory is induced to the system model, and the mathematic formula between the feedback channel rate and the closed-loop MIMO capacity are deduced. Through theoretical analysis and simulation results, this paper proposes four important conclusions on the relation between the feedback rate, the average SNR, the antenna number, and the closed-loop capacity. The conclusions, which are important to system design, provide the instructions to design and tradeoff the overhead of feedback channel and the capacity
