面向能效优化的MIMO系统参数配置
Parameter Settings of MIMO Systems for Energy Efficiency Optimization
摘要
Abstract
Based on the tensor model of point-to-point multiple-input multiple-output( MIMO) communica-tion systems,a joint optimization framework for the transmission parameters is proposed to maximize the ener-gy efficiency. Firstly,the tensor modeling procedure and the system energy efficiency model of the received signal are constructed with the signal matrix,coding matrix and channel matrix,respectively. Then,the k-rank condition of the parallel factor( PARAFAC) decomposition is exploited as the constraints to optimize the transmission parameters including the number of transmitting antennas,the number of receiving antennas,and the coding length by the iterative fitting method. Simulation results show that through the exhaustive search scheme,a set of optimal parameters can be found to maximize the energy efficiency of the system.关键词
