Description: 对于多输入多输出系统, 传统的基于训练序列的信道辨识方法为跟踪信道的变化, 必须
发送大量冗余信息, 传输效率较低 而基于子空间的纯盲方法又带有不可避免的模糊性, 辨识结果
精度不够。在子空间法的基础上, 利用少量训练符号估计出模糊矩阵, 以此矫正子空间法得到的结
果。仿真结果显示: 在保证辨识精度的前提下, 该方法减少了训练符号等冗余, 提高了传输效率。-In o rder to t rack the channel variat ion of MIMO OFDM sy stems, t radit io nal channel

Description: 本论文根据最小均方根误差准则（MMSE）,提出一种非正交设计导频的方法，这种方法在MASSIVE MIMO中非常有效。-In this letter, the error variance of the Minimal
Mean-Square Error (MMSE) channel estimator is analyzed, and
its analytic formula is given. Based on the analytic formula, a
designing criterion on the pilot signals is proposed. When training
time slots can be large enough, our criterion confirms the
well-known fact that orthogonal pilot signals are optimal. But if
training time slots are not enough to support this orthogonality,
our results show that the error variance is lower-bounded away
zero, no matter what kind of pilot signals are used. In this
case, the design of pilot signals should be implemented by using
the line packing on a complex Grassmannian manifold Platform: |

Description: 本文开发了一种自适应算法来估计mmWave信道参数，该算法利用了信道的较差散射特性。 为了使该算法有效运行，设计了一种新颖的分层多分辨率码本，以构造具有不同波束宽度的训练波束成形向量。 对于单路径信道，推导了使用所提出算法的估计误差概率的上限，并且获得了对算法自适应阶段之间训练功率的有效分配的一些见解。(This paper develops an adaptive algorithm to estimate the mmWave channel parameters that exploits the poor scattering nature of the channel. To enable the efficient operation of this algorithm, a novel hierarchical multi-resolution codebook is designed to construct training beamforming vectors with different beamwidths. For single-path channels, an upper bound on the estimation error probability using the proposed algorithm is derived, and some insights into the efficient allocation of the training power among the adaptive stages of the algorithm are obtained.)
