The book "USRP Amplifier For Underwater Acoustic Platform Using SDR" offers a comprehensive examination of the development of a Universal Software Radio Peripheral (USRP) for underwater acoustic platforms. It explains how an enhanced acoustic platform can improve the efficiency of information transmission between various underwater acoustic devices, such as autonomous vehicles and underwater profilers. The author, Haydar Sabeeh Kalash, presents a flexible and configurable modem design based on the Software Defined Radio (SDR) platform GNU Radio. A central element of this work is the amplifier specifically developed for the USRP, which demonstrates a significant improvement in transmission rate and the number of packets received in experiments. This technical book is aimed at professionals and students involved in the development and optimization of underwater communication systems.
