Robust Beamforming with Application in High-Resolution Sensing [PDF]

arXiv
As a fundamental technique in array signal processing, beamforming plays a crucial role in amplifying signals of interest while mitigating interference and noise. When uncertainties exist in the signal model or the data size of snapshots is limited, the performance of beamformers significantly degrades.

Codebook Design and Performance Analysis for Wideband Beamforming in Terahertz Communications [PDF]

arXiv
The codebook-based analog beamforming is appealing for future terahertz (THz) communications since it can generate high-gain directional beams with low-cost phase shifters via low-complexity beam training. However, conventional beamforming codebook design based on array response vectors for narrowband communications may suffer from severe performance ...

Maximum Signal Minus Interference to Noise Ratio Multiuser Receive Beamforming [PDF]

arXiv, 2017
Motivated by massive deployment of low data rate Internet of things (IoT) and ehealth devices with requirement for highly reliable communications, this paper proposes receive beamforming techniques for the uplink of a single-input multiple-output (SIMO) multiple access channel (MAC), based on a per-user probability of error metric and one-dimensional ...

2D Pre-Beamforming Control Method via Analog Radio Over Fiber for Wireless Communication Systems With Massive Planar Array Antenna

IEEE Access
To rapidly deploy large capacity wireless communication services using high frequency bands, a system is being considered that use radio-over-fiber (RoF) technology to separate the wireless base station function into a central station (CS) with signal ...
