Pulse position modulation (PPM) is a simple and effective technique for transmitting information via the underwater acoustic channel. In this paper engineering design considerations for an underwater acoustic PPM system, including the location of threshold and the effects of multipath, attenuation, and time dispersion, are discussed. Techniques for calculating the required transmitter power, pulse repetition rate, and pulse width to communicate over some specified geometry are given.
