多小区MIMO网络中一种新的D2 D通信干扰对齐算法
A new interference alignment algorithm for device-to-device communication underlaying multi-cell MIMO networks
摘要
Abstract
Integrate D2D technique into multi-cell MIMO(multiple-input multiple-output)network,a D2D-MIMO interfer-ence network is constituted.In order to eliminate the interference,a transmitting data streams allocation scheme based on the parity of the antennas number and the corresponding interference alignment algorithm is proposed in this paper.Firstly, this algorithm minimizes the interference power from the base station to non-targeted receivers,in order to design the pre-coding matrix of cellular link.And then Max-SINR(signal to interference plus noise ratio)criterion will be used to design the cellular link’s interference suppression matrix.Finally,the linear interference alignment can eliminate intra-interfer-ence and the Max-DOF(degrees of freedom)of this scheme can be obtained.The theoretical analysis and simulation results verify that,comparing with other interference alignment algorithms,the proposed algorithm improves the scheme’s degrees of freedom,spectrum efficiency and energy efficiency,and reduces the restriction for the number of antennas and enhances the flexibility of the system.关键词
