摘要: 研究了主网络和次网络都为单用户并联IC的并存时自由度。采用了干扰对齐、干扰中和以及感知网络相结合的干扰管理策略研究方法;对11种情况进行研究,并对每一种情况的干扰管理策略做了遍历分析,得出第11种情况自由度内界相对四用户IC有所增大;最终得出结论:并联两用户IC网间认知情况下自由度内界最大值为3。

关键词: 干扰信道,感知网络,自由度,干扰对齐,干扰中和

Abstract: This paper,applying a strategic research method combining interference alignment,interference neutralization and perception network together,studies the freedom degrees of IC when it is respectively paralleled with the main network and the sub-network,considering the cognition between the main network and the sub-network.It summarizes all the 11 cases in the related studies,makes an ergodic analysis of the interference management strategy of every case,and finally finds that,the IC of the inner bound freedoms in Case 11 have increased compared with 4 users.The final conclusion is that the inner bound freedom-degree maximum is 3 under the condition of IC inter-network cognition of two parallelusers.
