Cooperative MIMO transmission scheme for the DVB-T2 system
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.
