摘要

本文提出了基于奇异值分解(SVD)的码本设计准则来准确地恢复用户信道。因此，这些码本使得在HetNet环境中利用干扰减少辅助预处理技术实现实际目的成为可能。系统级仿真验证了所提出的基于SVD的码本恢复更准确的信道状态信息(CSI)，因为对于相同数量的反馈比特，非线性Tomlinson-Harashima (TH)预编码的性能优于零强制(ZF)预编码。

System-level performance evaluation of the SVD based codebooks in 3GPP LTE HetNet

This paper presents the singular value decomposition (SVD) based codebook design criteria to accurately recover the channel of the users. Therefore, these codebooks make possible to utilize the interference reduction aided preprocessing techniques for practical purpose as in the HetNet environment. The system-level simulations verify that the proposed SVD based codebooks recover more accurate channel state information (CSI) because the performance of non-linear Tomlinson-Harashima (TH) precoding is better than zero forcing (ZF) precoding for the same number of feedback bits.
