C-RAN架构中适用于干扰消除的资源分配机制
A Resource Allocation Mechanism for Interference Cancellation in C-RAN Architecture
摘要
Abstract
For the amplified background noise problem of the interference cancellation mechanism in the Clean-Radio Access Network( C-RAN) architecture wireless network,the interference over the whole sys-tem in the network can be solved by utilizing the centralized processing characteristic of C-RAN architec-ture. Based on the definition of the network amplification factor, the problem of minimizing the network background noise is modeled as an optimization mathematical problem,in which the resource allocation set is the feasible space and minimizing the background noise amplification factor is the target function. And then,the way of the applying genetic algorithm( GA) to solve the problem is given and the resource alloca-tion mechanism is designed. The simulation results show that applying the proposed mechanism in the C-RAN architecture can effectively reduce the bit error rate( BER) and improve the users’ fairness and net-work throughput.关键词
