The algorithm is based on the economic concepts of non-cooperative differential game, with interference constraint at the primary user. Based on the model, optimal power allocated to each secondary user for data transmission can be derived to maximize the secondary users' utilization. The algorithm can solve the interference problem between secondary users and primary user and achieve high power efficiency. It is shown by way of simulation that by introducing game theory in the power control algorithm, performance improvements can be obtained in terms of game theory in CR system.
