tailieunhanh - Performance analysis of DVB-NGH MIMO coded modulation system

Digital video broadcasting-next generation handheld (DVB-NGH) is the first broadcasting standard that incorporates multiple-input multiple-output (MIMO) techniques to overcome the Shannon limit of single antenna systems. This paper contributes to analyze the performance of the DVB-NGH MIMO coded modulation system. The detailed performance degradation from information-theoretic limit to implementation by average mutual information and extrinsic information transfer analysis is presented, which provides an insight guideline for future system improvement. Finally, bit error rate simulations are carried out to verify the analysis. | Performance Analysis of DVB-NGH MIMO Coded Modulation System Tao Cheng Kewu Peng Fang Yang and Zhixing Yang Research Institute Information Technology Electronic Engineering Department Tsinghua University Tsinghua National Laboratory for Information Science and Technology Beijing 100084 China National Engineering Laboratory for DTV Beijing 100191 China Email chengt10@ pengkewu fangyang yangzhx @ Abstract Digital video broadcasting-next generation handheld DVB-NGH is the first broadcasting standard that incorporates multiple-input multiple-output MIMO techniques to overcome the Shannon limit of single antenna systems.

Introduction Digital video broadcasting-next generation handheld DVB-NGH 1 is the handheld evolution of the second generation digital video broadcasting - terrestrial DVB-T2 standard. It was developed with the aim of being the reference mobile multimedia broadcasting standard outperforming existing first generation mobile TV terrestrial standard DVB-H in terms of capacity and coverage. The first edition of DVB-NGH draft was released by European telecommunications standards institute ETSI in June 2013 which contains four profiles including the base sheer-terrestrial profile and the multipleinput multiple-output MIMO terrestrial profile etc. Bit-interleaved coded modulation BICM 2 is employed as the basic coded modulation architecture of DVB-NGH. BICM consists of a forward .
