Towards the Next Generation Video Broadcasting
Résumé
Distributed multiple-input multiple-output (MIMO) is a promising technique for the future terrestrial TV broadcasting systems due to its higher efficiency over the traditional single-antenna transmission scheme. In this article, we investigate the application of distributed MIMO technique in the future broadcasting systems. We first show the advantage of the distributed MIMO from the channel capacity perspective. Then different space-time block codes (STBCs) that can be applied in the distributed MIMO broadcasting scenarios are discussed and compared with real system configurations and channel conditions. It is shown that the simple and sophisticated STBCs have mutually complementary application scenarios. Particularly, short 3D MIMO code is a good performance versus decoding complexity compromise among different application scenarios.
