This article discusses the using of various code structures in systems with cascaded multiple access Orthogonal Code Division Multiplexing - Orthogonal Chirp Division Multiplexing, the goal of determining signal-code structures that provide the best noise immunity in Waterson, Rayleigh, and underwater channels. The main purpose of research is to find out the data about Bit Error Rate for different cases of usage of popular types of noise immunity codes. All of these codes are used for reducing of the negative effects of various channels such as high rate of noise or fading etc. For every other channel the influence of these effects does vary. The results of the research would provide the information about the effectiveness of low-density-parity-check, polar and turbo product codes in different channels such as underwater, Rayleigh, Waterson.
