Investigation of Using De Bruijn Sequences Possibility in C-OChDM

Due to the rapid development of the Internet of Things technology and the need to use autonomous unmanned vehicles in the exploration of minerals, studying hard-to-reach terrain, such as the sea and freshwater bottom with a large number of suspended particles, including sand, algae, salt, etc., mines, remote regions, arctic deserts, there is a growing need for two things: the introduction of more noise-resistant communication systems, as well as an increase in the number of functioning devices. This article proposes to use the CodeOrthogonal Chirp Division Multiplexing cascade multiplexing technology to meet these conditions. The possibility of integrating De Bruijn sequences as expanding sequences for the first code cascade is considered. The indicator of the high-quality operation of this technology is the obtained bit error rate graphs obtained after the signal passes through the channel model describing salty sea water.
