Performance evaluation of 4×2 MIMO schemes for mobile broadcasting

Abstract

The utilization of multiple antennas in transmitters and receivers (MIMO) in communication systems allows for increased robustness of the received signal or increased bit rate. These both are important factors in the design of communication systems. The introduction of MIMO for broadcasting systems is currently considered for DVB-NGH (Digital Video Broadcasting Next Generation Handheld). In this paper the performance of selected Space Frequency Block Codes (SFBCs) is investigated in mobile environment with four transmitter and two receiver antennas. In addition, the effect of having a strong forward error correction code on top of SFBC is investigated by studying the effect of MIMO schemes on DVB-T2 (Second generation Terrestrial) based system.
