“…Even with the considerable advantages of this new waveform, its application in underwater systems has been little explored. A first attempt to analyze the use of GFDM in underwater acoustic communications systems was presented in [36], where mathematical expressions of the power spectral density were derived. This work presents the derivation of general analytical expressions to evaluate the performance of the GFDM waveform operating over underwater acoustic communication channels in terms of the out-of-band emissions and the symbol error probability.…”

The rapid growth of the Internet of Things (IoT) has extended its concept to underwater environments. However, the implementation of these systems via wired communication still represents a technological challenge, mainly due to the high cost of their deployment. Therefore, wireless communications are seen as an interesting solution for the deployment of underwater communications systems. Preliminary research indicated that underwater acoustic wireless communication could be used for some Internet of Underwater Things applications, mainly due to the wide range of communications involved. However, a significant disadvantage of acoustic systems is their low transmission data rate; thus, studies and analyses to improve this disadvantage must be carried out. Considering that new waveforms have been proposed to improve the performance of terrestrial wireless communications systems, this work presents the development of general analytical expressions that allow the performance evaluation of the Generalized Frequency Division Multiplexing (GFDM) waveform in underwater environments. These analytical expressions were obtained considering a continuous-time model for the GFDM signal and modeling the underwater acoustic communication channel as a time-varying multipath channel. Numerical results were obtained for many different systems and channel parameters, allowing a quantitative evaluation of the system performance degradation.

“…To reduce the computational overhead of simulating a GFDM system for the underwater channel, Hilario-Tacuri [27] came up with a set of closed-form mathematical equations. The expressions are then used to evaluate spectral efficiency in terms of OOB emissions for a GFDM system.…”
