Abstract
Nowadays pseudorandom sequences play a very important role in the majority areas and have many applications, for example, as spreading sequences for error-free transmitting, in our case they have found application in the generation of code words in the Galois field in base 3 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sup> . Using the Galois field in base 3 allows us to generate ternary Gordon-Mills-Welch sequences, which in turn aids to increase the structural security and noise immunity of the transmitted signal. This article discusses the algorithm for double information multiplexing to achieve greater noise-resistance of communication systems. The algorithm is based on widely explored orthogonal chirp division multiplexing technology, including for the purpose of introducing into 6G and the Internet of things.
