| Abstract: | Effective capacity describes the rate upper bound of the communication system under the quality of service(QoS) limitation. While the foregoing performance analysis focuses mainly on the single input single output and multiple input single output systems, this paper considers the effective capacity of the multiple input multiple output(MIMO) beamforming scheme. Given that the modulation(M-QAM or M-PSK) is restricted, we investigate the representative transmission scheme of MIMO beamforming: maximal ratio combining transmission, for which the closed-form formula of effective capacity is derived. Simulation results not only demonstrate the effectiveness of our performance analysis, but also show the relationship between effective capacity and average signal-to-noise ratio as well as the relationship between effective capacity and QoS parameter for various antenna configurations. |
