Performance Analysis of Turbo Coding Implementation In MIMO Based DVB-T2 System

Digital Video Broadcasting-Second Generation Terrestrial (DVB-T2) has been the most possible solution to implement digital television. It is the developed version of the last system that is known as Digital Video Broadcasting-Terrestrial (DVB-T). DVB-T2 system has superiority in data transmissions reliability with a high point-to-multipoint speeds. The combination of MIMO and OFDM has resulted in a high-speed data transfer system. Yet, a high-speed transmission could cause an Inter-symbol Interference (ISI) as the effect of frequency selective fading channels. In this research, simulation and performance analysis of Turbo Coding implementation on the MIMO-based DVB-T2 system were conducted. This system used the OFDM transmission technique to decrease ISI. The Turbo Code of this system was used as a Forward Error Correction (FEC) that was able to decrease the number of Bit Error Rate (BER). V-BLAST was also implemented as a detector and MMSE as a channel estimator. As a result, the Turbo Code ½ rate and the Turbo Code rate shows a decent performance on the MIMO-based DVB-T2 system. It was shown that the resulted BER was smaller compared to the system with no code.
