Abstract

The Digital Video Broadcasting second generation Terrestrial (DVB-T2) standard purposes to provide high definition digital video and high rate services for the same spectrum allocation of the current Digital Video Broadcasting Terrestrial (DVB-T) standard. The implementation guideline is provided by the DVB-T2 standardization community, the Digital Video Broadcasting (DVB) Project. The DVB Project is requesting the many submission technologies which could be considered as candidates for a second generation terrestrial transmission system. The most challenging requirements introduced by the DVB-T2 specification are an Fast Fourier Transform (FFT) size of up to 32k samples, 256-Quadrature amplitude modulation (QAM) and Low-Density Parity-Check (LDPC) coding with a block size of 64k bits. The increasing concern in Multiple-Input Multiple-Output (MIMO) systems has given rise to numerous research activities in recent years. In this paper, we propose the MIMO architecture and coded cooperative MIMO transmission scheme for DVB-T2 system. The simulation result of the proposal MIMO architecture in DVB-T2 system shows a definite performance improvement for coded cooperative MIMO system.

DVB-T2系统的协同MIMO传输方案

数字视频广播第二代地面广播(DVB-T2)标准旨在提供高清晰度数字视频和高速率服务，但频谱分配与目前的地面数字视频广播(DVB-T)标准相同。实施指南由DVB- t2标准化组织数字视频广播(DVB)项目提供。DVB项目正在征求许多可以作为第二代地面传输系统候选方案的提交技术。DVB-T2规范引入的最具挑战性的要求是高达32k采样的快速傅里叶变换(FFT)、256正交幅度调制(QAM)和64k位块大小的低密度奇偶校验(LDPC)编码。近年来，人们对多输入多输出(MIMO)系统的关注日益增加，引发了许多研究活动。本文提出了DVB-T2系统的MIMO结构和编码协同MIMO传输方案。该方案在DVB-T2系统中的仿真结果表明，编码协作式MIMO系统的性能得到了明显改善。
