煤矿井下基于博弈论CR节点协作通信研究

Study on cooperative working in cognitive radio communication nodes of coal mine applying game theory

现有无线通信系统在不同矿区通用性不强、通信效果不佳。煤矿井下认知系统可通过对煤矿井下通信环境参数的感知,对感知参数信息的融合、分析,利用动态博弈理论实现动态的频率选择、功率分配、调制方式等参数的调整,获得有效的通信效果和不同矿区兼容。通过Matlab进行了仿真验证,仿真结果表明:该算法能够快速收敛于系统稳定状态,而且,复杂度低,易于实现。

The existent wireless communication is not compatible in different diggings and the effect of communication is not good. The Cognitive radio communication system of coal mine needs to appereeive the parameter of the environment of wireless communication. By syncretizing and analyzing the perceptive message of environment of communication, dynamic game theory is used to implement the selection of frequency, power control and modulate model, and so on, it can gain effective communication effect and be compatible among different coal mine. Simulated by Matlab, simulation results show that the proposed scheme can converge to system stable status rapidly with low implementation flexibility.
