Resource distribution method for maximizing energy efficiency of multi-carrier distributed antenna system

The invention provides a resource distribution method for maximizing the energy efficiency of a multi-carrier distributed antenna system, and mainly solves the problem of joint design optimization ofsubcarrier distribution and antenna transmitting power control. According to the method, a reasonable multi-carrier distributed system power consumption model is established, a cooperative antenna setselection method based on received pilot signal strength is provided, and on the basis, the combined subcarrier distribution and power control optimization problem with the maximum system energy efficiency is solved through bisection search and a Lagrangian duality method. The method is applicable to a multi-carrier distributed antenna system, and the purpose of maximizing the energy efficiency of the system is achieved through joint distribution of resources such as antennas, subcarriers and transmitting power on the premise that the service quality requirement of a user is guaranteed. 本发明提出了一种最大化多载波分布式天线系统能效的资源分配方法，
