| Abstract: |
This paper presents a novel scheme for QoS guaranteed video transmission based on scalable video coding (SVC) over multi-input multi-output (MIMO) wireless systems. The proposed scheme is able to not only guarantee the QoS (required-BER of base and enhancement layer) and but also maximize the throughput. We assume that the estimated channel state information (CSI) at the receiver can be obtained at the transmitter through feedback. In this scenario, under a transmit power constraint, optimal power allocation can be achieved to satisfy QoS-guaranteed maximum throughput by a combination of several operations. These operations include singular value decomposition (SVD) for decomposing into equivalent parallel SISO channels, adaptive QAM-modulation, and channel adaptive sub-channel selection for base and enhancement layer transmission. We presented in this paper detailed analysis and simulation results to demonstrate that we can achieve QoS optimized video transmission over MIMO wireless systems based on scalable video coding. |
