  underwater
Implementation of an OFDM underwater acoustic communication system on an underwater vehicle with multiprocessor structure
      
Aimed at the real-time processing requirement of the OFDM algorithm, an underwater acoustic communication system with real-time processing capability is carried out.
      
An improved hypothesis-feedback equalization algorithm for multicode direct-sequence spread-spectrum underwater communications
      
In underwater acoustic communication, because the available bandwidth of the channel is severely limited, the direct-sequence spread-spectrum scheme can only be realized at low bit rates.
      
However, in this case, due to the rapid time-variability of the underwater channel, and the influence of inter-symbol interference (ISI) and inter-channel interference (ICI), the conventional rake receiver may fail to function.
