Decentralized resource sharing for multiple noncooperative underwater acoustic (UWA) communication links is investigated. Point-to-point links, considered as rational players, are involved in a noncooperative game in which they compete to find a tran

This paper investigates the signal-to-interference ratio and the achievable rates of underwater acoustic (UA) OFDM systems over channels where time and frequency dispersion are high enough that (i) neither the transmitter nor the receiver can have a

In underwater acoustic communications, the received signal is strongly affected by Doppler shift due to the relative motion between the transmitter and the receiver. The signal is received compressed or dilated making it hard to detect and synchroniz
