WebRegarding the modulation, DVB-T2 uses the sa me OFDM technique as DVB-T. Maintaining the 2K and 8K modes, the new standard has introduced longer symbols with 16K and 32K carriers in order to increase the length of the guard interval without de creasing the spectral efficiency of the system. The following characteristics have been devised for the T2 standard: • COFDM modulation with QPSK, 16-QAM, 64-QAM, or 256-QAM constellations. • OFDM modes are 1k, 2k, 4k, 8k, 16k, and 32k. The symbol length for 32k mode is about 4 ms. • Guard intervals are 1/128, 1/32, 1/16, 19/256, 1/8, 19/128, and 1/4. (For 32k mode, the maximum is 1/8.)

WebOrthogonal frequency-division multiplexing (OFDM) belongs to a broader class of multicarrier modulation (MCM) in which the data information is carried over many lower rate subcarriers.
