In this paper, we propose a novel joint source-channel coding (JSCC) scheme for scalable video transmission over multiple-input multiple-output (MIMO) systems. By exploiting the diversity of MIMO antennas and forward error correction (FEC)-based protection, our method aims to provide unequal error protection (UEP) for the video layers, which are mapped to appropriate antennas. Moreover, JSCC is also...
Video broadcasting is an efficient way to deliver video content to multiple receivers. However, due to heterogeneous channel conditions of users, it is challenging to minimize all users' video transmission distortion in MIMO broadcasting. In this paper, we investigate the channel scheduling problem, which maps Scalable Video layers to MIMO heterogenous channels to protect video layers unequally, so...
In this paper, we consider the inter-relay interference (IRI) problem in a two-path successive amplify-and-forward (AF) multi-input multi-output (MIMO) relay system. First, a new interference cancellation algorithm employed at the relays is proposed to fully remove the IRI with an arbitrary number of antennas. Second, the transmit beamforming matrix at the source, relays and destination are jointly...
In this paper, we investigate the antenna selection (AS) problem for scalable video streaming over MIMO wireless networks. By scheduling scalable video layers over MIMO antennas with different signal strength, the video layers are transmitted with un-equal error protections. Considering layer dependencies and various antenna conditions, it is a non-linear combinatorial problem for AS to minimize the...
This paper presents a non-cooperative method to maximize the throughput of a set of distributed links in wireless MIMO ad hoc networks. The space-time power scheduling in each link is built into a non-cooperative game where its utility function is identified and maximized. The link quality is introduced into the pricing function in order to obtain Pareto improvement. The gradient projection methods...
