Commercial enhanced version of sonic communication and commercial enhanced version of sonic Communication

Since the source code of sonic communication was released, we have received positive feedback. Thank you for your comments. This update greatly improves program compatibility, recognition rate, and stability. The recognition rate has exceeded most existing sonic communication programs in the market. Through customization, the program can realize the transmission of any character and length. In particular, many embedded developers are also very interested in acoustic waves. This time, we have optimized the limited CPU clock speed and memory size for Embedded Systems to run smoothly on a variety of embedded systems. Source code: Click to open the link

Principles and implementation of ultrasonic Communication

Xu tianzeng and Xu lufen from Xiamen University co-authored a book on underwater acoustic communication. You can look for graduation thesis from Xiamen University, such as Tong Feng and Xu xiangbin.
