В работе предложена методика расчета параметров результирующего дискретного канала для вторичных абонентов (SU) в системах когнитивного радио, образованного посредством алгоритма минимизации смен каналов, описываемых простой марковской цепью. Методика заключается в агрегировании графа, описывающего процесс работы алгоритма динамического занятия спектра SU. Получены математические выражения для определения переходных вероятностей графа, свернутого до двух состояний.

This paper considers the scenario when the resulting logical channel for a secondary user in a cognitive radio system is formed by the algorithm minimizing the number of physical channel changes. The stochastic activity of primary users in a physical channel is characterized by a simple Markov chain. We present the analytical method for forming an accurate stochastic model (a simple Markov chain) of the resulting logical channel. The method is based on the aggregations of the graph states describing the channel change process in the algorithm. The result of the method describes the stochastic availability of the resources for a secondary user in the formed logical channel.
