基于干扰对齐技术的无线通信系统设计
Design of Wireless Communication System Based on Interference Alignment
摘要
Abstract
Interference is the main restriction to the capacityof multi⁃user wireless communication system.The traditional method for interference management is orthogonalization,which split the radio resource for users.The larger the user number,the resource assigned to each user is less, leading to data rate per user declined significantly. Interference alignment ( IA ) is a novel signal processing technique which provides a useful method for improving the capacity of multi⁃user wireless communication system.In this paper,the bas⁃ic theory of IA is introduced.Then,the whole implementation scheme of IA is provided,including communication procedures,algorithm design,quantized channel state estimate and feedback method.Finally,the performance of IA is validated by simulation.关键词
