H.264/SVC codec provides spatial, temporal and quality scalabilities of the video information and MIMO systems offer multiple spatial sub channels to transmit different video layers. In this paper, we propose a joint source-channel coding scheme for the delivery of scalable video over Multi-Input-Multi-Output (MIMO) wireless systems. To improve the power efficiency of the MIMO system, we investigate...
In this paper, we propose a two-timescale delay-optimal dynamic clustering and power allocation design for downlink network MIMO systems. The dynamic clustering control is adaptive to the global queue state information (GQSI) only and computed at the base station controller (BSC) over a longer time scale. On the other hand, the power allocations of all the BSs in each cluster are adaptive to both...
This paper concerns delay analysis for Fair Power Allocation Strategy (FPAS) in multi antenna Broadcast Channel (BC). It is assumed the transmitter aims at sending individual information to a large number of single-antenna users (n) through a common wireless channel. Assuming there is a total transmit power constraint, the FPAS attempts to select the maximum number of active users in which each can...
In this paper, we consider delay-optimal MIMO precoder and power allocation design for a MIMO Link in wireless fading channels. There are L data streams spatially multiplexed onto the MIMO link with heterogeneous packet arrivals and delay requirements. The transmitter is assumed to have knowledge of outdated channel state information (CSIT) as well as the joint queue state information (QSI) of the...
