Propagation of sound pulse informational messages in planar wave-guide with ideal boundaries

Propagation of informational signal in the form of acoustic code-pulse sequence in the planar wave-guide with ideal walls and spatial structure is observed. It is discovered and observed some time and bit-error probability peculiarities for the informational message as a single and a pair of radio pulses with fre-quency distribution in dependency of the frequency ratio of pulses. Evaluation of probabilistic features was made for bit-error in variable of conditions where noise spectral density power is represented by noise of the sea at the selected frequency range. It is discovered and mapped some peculiarities and temporal characteristics of the acoustic single pulse propagation velocity to the assessment of the effects of energy transfer through the channel.Ref. 13, Fig. 15.
