Simulation System of Broadcasting Stream for T-DMB Receiver Test

The terrestrial DMB receivers and their application products need many tests such as normal reception, reception state for the noisy environment, reception state changes due to the changes of output power of the DMB signal, and reception state of various environment. Therefore, the real-time simulation system of the terrestrial DMB broadcasting system is a necessity to the terrestrial DMB research institutions. manufacturers, and other related organizations. In the paper, we design the DMB simulation system, which generates the real-time streams of terrestrial DMB broadcast signals and simulates the real DMB broadcasting signals. The system consists of T-DMB signal generator with PCI interface and simulation software for various functional components of program. The study reveals that the implementation of software-based T-DMB simulation system is possible with low cost. Through various experiments, we evaluate the performance of the simulation system, and we provide the future directions of research.
