WebJun 27, 2012 · Frequency synchronization, arises from the different frequencies of local oscillators of the transmitter and the receiver, this will destroy the OFDM demodulation, so we have to determine the difference between carrier frequencies to compensate for it. Many algorithms based on pilots are used to detect for the frequency offset. Jun 27, 2012 #6 E WebPerformance of OTFS and OCDM Schemes in Underwater Acoustic Communication Channels Abstract: Signaling schemes robust to large Doppler shifts are needed for reliable underwater acoustic (UWA) communication, and orthogonal time frequency space (OTFS) and orthogonal chirp division multiplexing (OCDM) are two promising schemes in this …
