为应对毫米波通信加入智能反射表面(IRS)进行辅助通信导致系统变复杂难以获得信道状态信息(CSI)这一挑战,采用了混合智能反射表面结构,即IRS由大量无源元件和有限的射频(RF)链构成,其中有限的RF链用来估计基站/终端和IRS之间的信道。基于该结构,提出一种信道估计方案。该方案根据有限的RF链,首先使用一种改进的多信号分类算法对信道的离开角和到达角同时进行估计,然后提出一种复数并联深度神经网络对路径增益进行估计。通过将所提方案和其他方法进行仿真比较,证明了所提方案的优越性。
When adding intelligent reflecting surface (IRS) for assist communication in millimeter wave communication
the system becomes complicated and difficult to obtain channel state information (CSI).To solve these challenges
a hybrid intelligent reflecting surface structure was adopted
that is
the IRS was composed of a large number of passive elements and the limited radio frequency (RF) chains
where the limited RF chains were used to estimate the channel between the base station/terminal and the IRS.Based on the structure
a channel estimation scheme was proposed
which was based on the limited RF chains.First
an improved multiple signal classification algorithm was used to estimate the departure angle and arrival angle of the channel at the same time
and then a complex parallel deep neural network was proposed to estimate the path gain.Through simulation and comparison between the proposed scheme and other methods
the superiority of the proposed scheme is proved.
