摘要/Abstract

摘要：

针对具有反馈时延的单小区多用户MIMO蜂窝干扰网络，采用时延度（DoD）来量化干扰对齐方案引起的信息时延，提出一种基于偏袒干扰消除的回溯干扰对齐（PIE-RIA）方案。该方案首先在中继处获取干扰符号并设计预编码矩阵，然后中继发送已编码的干扰符号至用户执行干扰消除，最后基站利用反馈的干扰信号与CSI实现多个用户的回溯干扰对齐。仿真结果表明，PIE-RIA方案在保留自由度（DoF）增益的同时降低了DoD，保证了时延敏感网络中信息传输的实时性。

Abstract:

For interference networks, the degree of delay (DoD) was proposed to quantify the information delay among traditional interference alignment (IA) schemes.It indicated that networks suffer from the issue of latency caused by IA schemes.Herein, for the MIMO downlink broadcast channel (BC), the partial interference elimination based retrospective interference alignment scheme (PIE-RIA) was put forward.In the scheme, relay technique was adopted to eliminate partial interference signals so that part of desired symbols could be decoded promptly in user sides.Meanwhile, in the last slot, the eliminated signals could be regenerated in base station side with the retrospective interference alignment (RIA) scheme .The simulation results show that PIE-RIA scheme maintains degree of freedom (DoF) gain of RIA scheme and in the meantime, achieves lower DoD than the other schemes.

Key words: delay sensitive network, retrospective interference alignment, partial interference elimination, degree of freedom, degree of delay
