Reliable and energy-efficient cooperative OFDM communications over underwater acoustic channels
Underwater acoustic sensor networks (UWASN) have been attracting growing research interests in recent decades due to various promising applications. Underwater acoustic communications (UAC), which adopts acoustic waves as the information carrier, is one of the key communication techniques to realize UWASN. However, UAC is very challenging due to low carrier frequency, distance-dependent bandwidth, large delay spread, long and variable propagation delay, and doubly-selective fading. In this research, we will consider cooperative communications to improve the reliability and energy efficiency of ...
