提出了一种联合信道分配与功率控制算法，通过优化目标将家庭网络的信道分配和功率控制结合，限定干扰范围，采用凸优化和次梯度方法，求解出功率的闭合式，优化了家庭网络的容量。算法又将家庭网络容量与宏网络容量联系，使宏网络容量得到了提升。仿真结果表明，与单纯的功率控制算法相比，所提算法提高了系统容量。

A joint channel allocation and power control algorithm was proposed, which used convex optimization method to combine channel allocation and power control and limit the range of interference, subgradient method was used to solve the close formula of power and optimize the capacity of fem network. In addition, the algorithm had connected the optimal of fem network and macro network together, thus macro network’s throughput could be maximized. Simulation results prove that system throughput has been greatly improved.
