Engineering Workstation for the Chief Designer of Radio Electronic Means Based on the Theory of Multi-Agent Systems

Abstract

The possibility of creating an engineering workstation for the chief designer of radio electronic means with elements of an expert system based on a multi-agent system is considered. The functions of the engineering workstation and the knowledge base necessary for its work are considered. A separate agent is seen as a mechanism that can influence the achievement of the goal and decision-making. Each of the agents solves the problem, but is able to exchange information with each other. To organize the process of problem decomposition in multi-agent systems, either a distributed problem-solving system or decentralized artificial intelligence is created. Agents in the process of working out their functions form a list of performed actions, testing and verification results and send it to the control system. Depending on the tasks to be accomplished, each of the agents can use different technologies and mathematical apparatus. The problem of making the optimal solution is considered using the example of the communication and communication channel interaction model. A radiotelephone system operating in a duplex mode and having two communication channels, direct and reverse, is considered. A forward channel is used for transmitting messages from a base station to a subscriber station. The transmission of messages from the subscriber station to the base station is carried out on the reverse communication channel. For each channel, the control parameters are defined. A command to control the quality of the reverse link is transmitted on the forward channel and vice versa. A model of an adaptive radio system is presented in the form of a system of equations. The dependence of the probability of a correct reception of a message on the error probability in a symbol computed by the proposed algorithm is given.
