qDigital Sonar Design in Underwater Acoustics Principles and Applicationsq provides comprehensive and up-to-date coverage of research on sonar design, including the basic theory and techniques of digital signal processing, basic concept of information theory, ocean acoustics, underwater acoustic signal propagation theory, and underwater signal processing theory. This book discusses the general design procedure and approaches to implementation, the design method, system simulation theory and techniques, sonar tests in the laboratory, lake and sea, and practical validation criteria and methods for digital sonar design. It is intended for researchers in the fields of underwater signal processing and sonar design, and also for navy officers and ocean explorers. Qihu Li is a professor at the Institute of Acoustics, Chinese Academy of Sciences, and an academician of the Chinese Academy of Sciences.6.8.2 Coding and Decoding The binary code cannot be directly transmitted underwater, since the front margin and rear margin of the binary code are both very sharp and will occupy a very wide frequency band. Therefore it is necessary to use a modulation ... The increase in redundancy will decrease the error code rate and increase the error correcting ability. The coding technique is necessary not onlyanbsp;...
