Webthe 2k mode of the DVB-T standard. This particular mode is intended for mobile reception of standard definition DTV. The transmitted OFDM signal is organized in frames. Each frame … 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.)
