description: In this paper, was studied the construction of a digital radio communication system using the volume of the alphabet m and phase-shifted complex signals. A system with m = 8 is proposed, which allows one to achieve an increase in the information transfer rate by 3 times in comparison with the traditional binary (m = 2). To ensure noise immunity in the developed system, it is proposed to use the Reed-Solomon block code (63,53,5). The paper presents the structural and functional diagrams of the equipment of the radio line. Of particular difficulty is the construction of a receiving device. In the course of the work, the work of the developed system was simulated and the sea channel of radio communication was analyzed. Taking into account the factors that are characteristic of the maritime radio channel, the calculation of the communication distance between objects for three cases of their location has been carried out. The obtained values of the maximum communication range are 243 km, 367 km, 43 km, respectively. The developed m-ary radio communication system can be used as a multi-station data transmission system via a multiple access group radio channel with network exchange principles based on the time division of subscriber channels.
