Abstract
Digital Video Broadcasting-Terrestrial second generation (DVB-T2) is developed from Digital Video Broadcasting — Terrestrial first generation (DVB-T) standard. DVB broadcasting development based is still open. In this research, the development or evaluation of MIMO-OFDM system which is a transmission technique used in the DVB-T2 standard. Multiple Input Multiple Output (MIMO) techniques using multiple antennas at the transmitter side and receiver side for increase communications capabilities. Modulation technique for wireless communication that is chosen is Orthogonal Frequency Division Multiplexing (OFDM), with the purpose of reliable large data supplying in radio channel. Increased the model of channel estimation at the receiver side to determine system performance DVB-T2. Channel estimation used Minimum Mean Square Error (MMSE) algorithm, while the detector configuration using Zero Forcing (ZF). From the analysis results, the channel attenuation of subcarrier curve and the Bit Error Rate (BER) as a function of Signal to Noise Ratio (SNR) curve stating the results of the comparison value of channel estimation and ideal channel with the results obtained from the simulation is similar approach. The performance of system is described by BER over SNR curve.
