Abstract	In this paper, we present a novel QoS guaranteed scalable video transmission scheme over multi-input multi-output (MIMO) wireless systems. The proposed scheme is able to not only guarantee the QoS (required BER for base and enhancement layer in compressed video) and but also maximize the system throughput over time-varying MIMO channel. We assume that the estimated channel state information (CSI) at the receiver is available at the transmitter through feedback. In this scenario, under a transmit power constraint, optimal power allocation can be designed to satisfy QoS-guaranteed maximum throughput by a combination of several adaptive operations. These operations include channel adaptive sub-channel selection, power allocation based on water-filling (WF), and data rate maximizing power reallocation. The proposed power reallocation scheme enables us to obtain surplus power after selecting proper adaptive mode and reallocate to other subchannels so as to maximize the data rate. We present in this paper some detailed analysis as well as simulation results to demonstrate that QoS guaranteed video transmission over MIMO wireless systems can indeed be achieved based on scalable video coding and a sequence of adaptive operations.
