In mmWave massive MIMO, the required number of radio frequency (RF) chains becomes impractical due to the expensive and power-hungry components such as variable gain power amplifiers, filters, mixers, and analog-to-digital/digital-to-analog converters (ADCs/DACs). A promising solution to this problem is reducing the number of radiofrequency (RF) chains

Hybrid analog digital beamforming
2022In recent years, two of the main trends in wireless communication have been higher carrier frequencies and larger antenna arrays. Each trend by itself allows for a significant gain in system performance, but they are difficult to combine. The former trend, higher carrier frequencies in the millimeter-wave (mm-wave) range, offers an unprecedented ...

Hybrid beamforming: reduced eigen beamforming on beam signals
2002 International Zurich Seminar on Broadband Communications Access - Transmission - Networking (Cat. No.02TH8599), 2003A hybrid beamforming technique for multiple antenna receivers is introduced. It is a combination of a simple fixed beam method and the adaptive eigen beamforming algorithm. This two-stage solution allows for a user-specific scalable trade-off between performance and complexity, depending on the interference scenario.

Analysis of diversity, beamforming and hybrid diversity-beamforming systems
2003 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2003. Proceedings. (ICASSP '03)., 2004In this paper we compare Shannon capacities of diversity, beamforming, and hybrid diversity-beamforming systems for reverse and forward links. Our results show that the reverse link capacity of a diversity system is higher than that of a beamforming system, while the beamforming system can provide higher capacity than the diversity system in the ...
