This paper proposes doubly differential orthogonal frequency division multiplexing (OFDM) for underwater acoustic communications (UWACs). UWAC channels suffer from severe time and frequency selectivities, i.e., double selectivity. OFDM is a good solution for frequency selectivity and differential encoding/differential detection (DE/DD) is a good solution for time selectivity. However OFDM suffers from intercarrier interference (ICI) due to its narrow subcarriers spacing. Intercarrier Interference Self-Canceller (ICISC) can cancel ICI for differential OFDM, but DE/DD can not cope with severe time selective channels. In order to solve these issues, this paper proposes doubly differential OFDM employing the ICISC for severe doubly-selective channels. Finally, computer simulation results confirm that the proposed doubly differential OFDM has good performance for severe doubly-selective channels. |
