5G 毫米波信道估计研究综述. (Chinese)

Channel estimation is one of the key techniques of massive multiple-input multiple-output(MIMO) millimeter wave(mmWave) systems. The channel estimation strategies of massive MIMO mmWave in recent years are combed, focus with on the description and analysis from the three aspects of compressed sensing, parameter estimation, and deep learning. Through performance comparisons of algorithms, the current problems and the future development trends of mmWave channel estimation are summarized. [ABSTRACT FROM AUTHOR]
