The underwater communication technique based on MBFSK (Multiple Binary Frequency Shift Keying) modulation is used in challenging propagation conditions. Despite the band-width limitations present underwater, it provides stable underwa-ter connectivity. This paper presents a hardware implementation of the MBFSK modulation technique for underwater wireless communications. The implementation was carried out using an FPGA-based programmable logic device. The concept of the device design, the hardware solution, and the firmware descrip-tion are presented. An overview and diagram of the underwater communication system are also provided. The transceiver system was tested in the tank of the Hydroacoustics Laboratory of the Gdynia Maritime University, and the results are presented and discussed. The aim of this work is to present the design, software algorithm, and test results of the developed underwater communication system.
