Cooperative multi-AUV localization has the potential to outperform single-AUV localization, by taking advantage of data sharing among the team members. Unlike terrestrial communication links, underwater communication links have many issues pertaining to the channel stability and bandwidth, and therefore a decentralized localization is preferred. However this opens up new challenges to team members...
Single Input Single Output (SISO) Orthogonal Frequency Division-Multiplexing (OFDM) over short to medium range shallow water channels suffers from low bandwidth efficiency. This happens due to large Cyclic Prefix (CP) and relative small number of sub-carriers. To increase the bandwidth efficiency, a time domain channel shortening equalizer (CSE) can be inserted before the Fast Fourier Transform (FFT)...
The past three decades have seen a growing interest in underwater acoustic communications. Continued research over the years has resulted in improved performance and robustness as compared to the initial communication systems. Research has expanded from pointtopoint communications to include underwater networks as well. A series of review papers provide an excellent history of the development of the...
