Double Layer Space-Time Block Code for Hybrid Satellite-Terrestrial Broadcasting Systems

Multiple Input Multiple Output (MIMO) is a topic of high interest for the next generation of broadcasting systems. However, their deployment in single frequency networks (SFN) becomes more critical when they are used in hybrid satellite-terrestrial transmission due to the different aspects of the respective transmission links. In this paper, we propose to apply a double layer space time block code (DLSTBC) for MIMO schemes in this hybrid transmission. The proposed scheme is based on a layered construction designed to be efficient in line of sight (LOS) situation but also in deep shadowing. It is then a very promising candidate for next generation handheld broadcasting systems and SFN architecture.
