System analysis of the cognitive radio system operation algorithm efficiency

Abstract

The report presents an algorithm for optimal control of a cognitive radio communication system. The algorithm is based on the application of decision-making criteria in a dynamic environment. The basis of the algorithm is to solve the problem of maximizing the system efficiency coefficient in a given mode. Thus, the cognitive radio communication system can choose the most optimal mode of operation, both in a specific situation, and choose the general preferred mode of operation for a comprehensive assessment of the external situation. From the effectiveness of the radio system in analog and digital modes, we can conclude that in the event of time limitations it is more useful to control the transmitter power (increase the energy of the radio line). However, when working in digital modes, the decrease in efficiency is much slower than when using analog modes. An analysis of the operation under conditions of restrictions on the transmission power also shows a slower decrease in efficiency in digital modes with slow consumption of resources, while consumption increases sharply in analog mode.
