Performance Analysis of MIMO Detection Techniques in DVB-T2 Systems

Abstract

Digital Video Broadcasting-Terrestrial Second Generation (DVB-T2) is a digital television broadcasting system that is being implemented in the world. This system can send large amounts of data at high point-to-multipoint speed. Multiple Input Multiple Output (MIMO) is a transmission technique that is implemented in many new technologies nowadays. This technique can increase the data rate without increasing the bandwidth. In this study, a DVB-T2 system simulation was made by applying 2x2 MIMO-OFDM technology. For better system performance, it is necessary to use a detector to minimize the noise in the data transmission process. In this study, simulations and analyzation were performed to determine the performance of MIMO detectors on a DVB-T2 system. The analysis was done by comparing the BER curve to the generated SNR value by each detector system. The simulation results show that the Vertical Bell Labs Layered Space-Time/Minimum Mean Square Error (V-BLAST/MMSE) detection technique is the best technique in improving system performance, followed by V-BLAST/ZF, Minimum Mean Square Error (MMSE), and Zero Forcing (ZF) detectors.
