Double Differential OFDM Employing an Intercarrier Interference Self-Canceller for Underwater Acoustic Communications
Yuka Tanaka, Yui Nakai, Hiroshi Kubo (Ritsumeikan Univ.) RCS2019-85
Abstract (in Japanese) (See Japanese page) 
(in English) 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.
