Joint Optimization of Coverage and Capacity based on Power Density Distribution in Heterogeneous Cellular Networks

摘要：

　　The paper presents a joint optimization algorithm for coverage and capacity in heterogeneous cellular networks.A joint optimization objective related to capacity loss considering both coverage hole and overlap area based on power density distribution is proposed.The optimization object is a NP problem due to that the adjusting parameters are mixed with discrete and continuous,so the bacterial foraging (BF) algorithm is improved based on network performance analysis result to find a more effective direction than randomly selected.The results of simulation show that the optimization object is feasible gains a better effect than traditional method.
