Orthogonal Frequency Division Multiplexing (OFDM) is a powerful technique employed in communications systems to combat with the frequency selective channel. Combined with smart antennas (multiple antenna system) at the transmitter and receiver, OFDM proves to be robust against channel delay spread. Moreover, it leads to significant data rates with improved bit error performance over links having only a single antenna at both the transmitter and receiver. In this work, the performance of the 2nd Generation Terrestrial Digital Video Broadcasting (DVB-T2) is analyzed, where high data rate is a must. To analyze this system, OFDM with Multiple-Input Multiple- Output (MIMO) systems have been used by applying an algorithm called Space-Time Block Code (STBC). Here, bit error rate (BER) of the system is analyzed in Additive White Gaussian Noise (AWGN) channel using QPSK modulation scheme. It has also been proved in this work that, the combination of OFDM-MIMO system is much more bandwidth efficient compared to normal OFDM system.
