Two-Timescale Channel Estimation for Reconfigurable Intelligent Surface Aided Wireless Communications
Chen Hu, Linglong Dai
Channel estimation is challenging for the reconfigurable intelligent surface (RIS)-aided wireless communications. Since the number of coefficients of the cascaded channel among the…
Deep Learning for Beamspace Channel Estimation in Millimeter-Wave Massive MIMO Systems
Xiuhong Wei, Chen Hu, Linglong Dai
Millimeter-wave massive multiple-input multiple-output (MIMO) can use a lens antenna array to considerably reduce the number of radio frequency (RF) chains, but channel estimation…
Super-resolution channel estimation for mmWave massive MIMO with hybrid precoding
Chen Hu, Linglong Dai, Talha Mir +2
Channel estimation is challenging for millimeter-wave (mmWave) massive MIMO with hybrid precoding, since the number of radio frequency (RF) chains is much smaller than that of ante…
Channel Estimation for Millimeter-Wave Massive MIMO with Hybrid Precoding over Frequency-Selective Fading Channels
Zhen Gao, Linglong Dai, Chen Hu +1
Channel estimation for millimeter-wave (mmWave) massive MIMO with hybrid precoding is challenging, since the number of radio frequency (RF) chains is usually much smaller than that…
