WebOrthogonal Frequency Division Multiplexing (OFDM) is the multicarrier digital modulation technique used by modern wireless communications systems such as 5G and LTE cellular, and WiFi. The advantages of OFDM over other techniques, such as single carrier QAM, include support of higher data rates with a simpler receiver design. 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,
