Cost-Effective Millimeter Wave Communications with Lens Antenna Array [article]

Yong Zeng, Rui Zhang
<span title="2016-10-08">2016</span> <i > arXiv </i> &nbsp; <span class="release-stage" >pre-print</span>
Numerical results show that the lens-based system significantly outperforms the state-of-the-art designs for mmWave systems in both spectrum efficiency and energy efficiency.  ...  However, the large number of antennas used and the wide signal bandwidth in mmWave systems render the conventional multi-antenna techniques increasingly costly in terms of signal processing complexity,  ...  ACKNOWLEDGEMENT The authors would like to thank Zhi Ning Chen and Shunli Li in the National University of Singapore for helpful discussions as well as the help to produce Fig. 3 .  ...

Unsupervised Learning Based Hybrid Beamforming with Low-Resolution Phase Shifters for MU-MIMO Systems [article]

Chia-Ho Kuo, Hsin-Yuan Chang, Ronald Y. Chang, Wei-Ho Chung
<span title="2022-02-04">2022</span> <i > arXiv </i> &nbsp; <span class="release-stage" >pre-print</span>
In this paper, we propose an unsupervised-learning-based scheme to jointly design the analog precoder and combiner with low-resolution PSs for multiuser multiple-input multiple-output (MU-MIMO) systems  ...  Existing hybrid beamforming designs based on infinite-resolution phase shifters (PSs) are impractical due to hardware cost and power consumption.  ...  In [8] , a low-complexity hybrid precoding and combining design with two-bit resolution PSs for MU-MIMO systems was developed.  ...

Hybrid MIMO Architectures for Millimeter Wave Communications: Phase Shifters or Switches? [article]

Roi Méndez-Rial, Cristian Rusu, Nuria González-Prelcic, Ahmed Alkhateeb, Robert W. Heath Jr
<span title="2015-12-09">2015</span> <i > arXiv </i> &nbsp; <span class="release-stage" >pre-print</span>
Hybrid analog/digital MIMO architectures were recently proposed as an alternative for fully-digitalprecoding in millimeter wave (mmWave) wireless communication systems.  ...  Using the estimated, we develop two algorithms for the design of the hybrid combiner based on switches and analyze the achieved spectral efficiency.  ...  SYSTEM MODEL Consider the single-user mmWave hybrid MIMO system in Fig. 1 .  ...
