摘要

本文介绍了基于DVB-T(数字视频广播地面)标准的广播信道(下游)和基于新型同步频分多址(SFDMA)技术的返回信道(上游)的地面交互系统的定义和原型设计的结果。该系统是在欧洲ACTS iTTi项目框架内构思和实施的。该方法是将国内DVB-T接收机的低比特率数据发送回UHF频段内的广播公司。本项目针对接收机的VLSI实现进行了系统规格、完整的硬件原型设计和复杂性估算。

Wireless terrestrial interactive system based on DVB-T and SFDMA; the iTTi project

This paper presents the results of the definition and prototyping of a terrestrial interactive system based on the DVB-T (digital video broadcasting terrestrial) standard for the broadcast channel (downstream) and the novel synchronous frequency division multiple access (SFDMA) technique for the return channel (upstream). The system has been conceived and implemented in the framework of the European ACTS iTTi project. The approach is to transmit bursts of low bit rate data from domestic DVB-T receivers back to the broadcaster within the UHF band. System specification, complete hardware prototyping and complexity estimation in view of VLSI implementation of the receiver has been carried out within the project.
