| Abstract: | In terms of the problems such as the mutual interference existing in the communication of major and minor signals in the mine wireless communication, centralized power allocation algorithm was proposed. The power allocation system model was established, and the object function of power allocation at the relay node was listed, in order to maximize and minimize the system weighted rate. Also analysis was made on the power allocation of centralized system, turning the issue into the special minimized and maximized ones to get the optimized solutions, to minimize the interference of mutual signals. The algorithm was used in the actual mine communication test, and the simulation analysis was made on the test data, showing the allocation method is correct and practicable. |
