This paper presents a novel smart downlink scheduling scheme to enhance the performance of multimedia transmission over long-term evolution (LTE) networks. LTE represents a promising framework for the next-generation broadband multimedia services because of its significantly increased data rate over 3G cellular networks. However, the current LTE scheduling scheme has largely been designed for general...
We present in this paper a new device-to-device (D2D) communication scheme to create a QoS enhanced multimedia services for LTE users who are physically close to each other. This scheme has a potential to provide higher bandwidth service with reduced delay and reduced power consumption. However, a significant challenge from such D2D opportunity is to establish the direct link between nearby devices...
Long-term evolution (LTE) represents a promising technique for ubiquitous multimedia communication because of its significant enhancement to the data transmission rate. However, the hard hand-off (HO) procedure standardized in LTE is a menace to multimedia quality of service (QoS), due to the service interruption introduced by the procedure. Thus, one major challenge of such a system is to design...
This paper investigates fairness and quality of service (QoS) guaranteed user scheduling scheme in multi-user MIMO broadcast channel. The main contribution of this paper is to consider characteristic of video source in user scheduling process. As a result, the proposed scheme can provide fair and satisfactory services to regular data users, while QoS of multimedia consumers is guaranteed. Since video...
A prioritized spatial multiplexing scheme has recently been developed for the transmission of scalable video coded (SVC) video over MIMO systems. One unique feature of this scheme is its capability to channelize the sub-channels according to the importance of the individually transmitted data streams. We consider in this research a challenging task of providing high quality multimedia services over...
Spatial multiplexing MIMO wireless system is an excellent choice for next generation broadband multimedia communications because of its parallel transmission capability. A major challenge for such MIMO system is that it usually requires appropriate decomposition of both wireless channels and multimedia data bitstreams. Existing approaches to MIMO channel decomposition have been passively based on...
