Research of the Convolutional and Product Turbo Codes Characteristics in Conditions of Underwater Channel

Acoustic underwater communication is a promising direction in the development of communication systems with underwater objects, requiring the development of the applied signal code structures. This research aims to find the optimal turbo coding solution for improving noise immunity in underwater communications with orthogonal chirp modulation. This problem is relevant in several areas: for underwater monitoring, highly reliable communications with far remote subscribers as well as for the Internet of things – for normal functioning of ultra-low power water purity sensors.
