基于中继的低延时无线协作视频传输系统
Low Delay Wireless Cooperative Video Transmission System Based on Relays
摘要
Abstract
In wireless video transmission system, the length of the frame changes and the source bit rate varies during the transmission. To reduce the system delay, this paper proposes a low delay wireless cooperative video transmission system with relays. The system delay is formulated and the reason of the delay reduction is analyzed. To improve the quality of the video transmission, a relay strategy and modulation and coding scheme are introduced for the system. The simulation results demonstrate that the transmission system can effectively reduce the video transmission delay and the Bit Error Rate(BER).关键词
