9th IEEE Workshop on Multimedia Signal Processing
作者: Stoufs, M. Munteanu, A. Cornelis, J. Schelkens, P. Vrije Univ Brussel Dept Elect & Informat ETRO Interdisciplinary Inst Broadband Technol IBBT B-1050 Brussels Belgium
In this paper, we propose a joint source-channel coding (JSCC) methodology which minimizes the end-to-end distortion for the transmission of H.264/MPEG-4 scalable video over packet loss channels. The proposed JSCC-app... 详细信息

IEEE TRANSACTIONS ON INFORMATION THEORY 2011年 第9期57卷 5660-5672页
作者: Gao, Yang Tuncel, Ertem Univ Calif Riverside Dept Elect Engn Riverside CA 92521 USA
A new hybrid digital/analog scheme is proposed for lossy transmission of a Gaussian source over a bandwidth-matched Gaussian broadcast channel with source side information available at each receiver. The proposed sche... 详细信息

IEEE TRANSACTIONS ON COMMUNICATIONS 2011年 第12期59卷 3335-3342页
作者: Behroozi, Hamid Alajaji, Fady Linder, Tamas Queens Univ Dept Math & Stat Kingston ON K7L 3N6 Canada
We consider the problem of sending a bivariate Gaussian source S = (S-1, S-2) across a power-limited two-user Gaussian broadcast channel. User i (i = 1, 2) observes the transmitted signal corrupted by Gaussian noise w... 详细信息

作者: Kumar, K. Raj Caire, Giuseppe Ecole Polytech Fed Lausanne La Algorithm CH-1015 Lausanne Switzerland Univ So Calif Ming Hsieh Dept Elect Engn Los Angeles CA 90089 USA
In order to exploit the full multiplexing gain of multi-antenna multi-user downlink schemes, accurate channel state information at the transmitter (i.e., at the base station) is required. We consider the design of a c... 详细信息
