Distributed MIMO schemes for the future digital video broadcasting

Abstract

Abstract-This paper studies the application of distributed multiple-input multiple-output (MIMO), i.e. MIMO transmission over several geographically separated but cooperated transmitters, for future TV broadcasting systems. It is first shown that distributed MIMO is promising for the future broadcasting systems from a channel capacity perspective. Several STBCs that can be applied in the distributed MIMO broadcasting scenarios are then discussed. Through performance comparison and complexity analyses with realistic system settings and channel model, it can be concluded that simple STBCs are efficient for low data rate applications, while the sophisticated ones are more suitable to deliver high data rate services.
