Each frame … WebOFDM) which has been adopted, for instance, in the WiMedia solution for ultra wide band (UWB) context [9]. The resulting signal can then be demodulated using the estimation methods developed for ZP-OFDM, as proposed in [8] for example. Chinese DTMB standard (multicarrier mode) is somewhat similar to DVB-T in terms of OFDM transmission scheme,

WebIn digital terrestrial television (DVB-T, DVB-H and similar techniques) OFDM modulation is used; i.e., multi-carrier modulation. The above symbol rate should then be divided by the number of OFDM sub-carriers in view to achieve the OFDM symbol rate. See the OFDM system comparison table for further numerical details.
