Online and Offline Deep Learning Strategies For Channel Estimation and Hybrid Beamforming in Multi-Carrier mm-Wave Massive MIMO Systems

20 Dec 2019Ahmet M. ElbirKumar Vijay MishraM. R. Bhavani ShankarBjörn Ottersten

Hybrid analog and digital beamforming transceivers are instrumental in addressing the challenge of expensive hardware and high training overheads in the next generation millimeter-wave (mm-Wave) massive MIMO (multiple-input multiple-output) systems. However, lack of fully digital beamforming in hybrid architectures and short coherence times at mm-Wave impose additional constraints on the channel estimation... (read more)
