摘要:

在现有室内分布系统建设模式的基础上,针对4G室内分布系统改造过程中的MIMO(Multiple Input Multiple Output)双通道功率平衡问题建立了数学模型,并采用MOEA/D-M2M进化算法进行求解.仿真结果表明,本文设计的模型和算法能求解出一种同时满足建网成本最小化和室内覆盖最大化的方案.

关键词: 室内分布系统; MIMO双通道; 进化算法

Abstract:

In order to maintain MIMO dual-channel power balance in reforming 4G network indoor distributed system, this paper analyses the construction mode of the present indoor distributed system, then establishes a mathematical model and designs an algorithm based on MOEA/D-M2M. The experimental results demonstrate that our mathematical model and algorithm can obtain an optimal solution which aims to minimize the device cost while maximizing the indoor coverage.

Key words: indoor distributed system; MIMO(multiple input multiple output) dual-channel mode; evolutionary algorithm
