Beam-based uplink multi-user detection for mmWave communications

The UEs are partitioned into groups according to their beam-channel characteristics. On the beam domain, we will design the uplink data detection in a per UE-group basis. At BS, a total of

How to Select the Perfect Beam Splitter for Your Optical Setup

Beam splitters play a vital role in optical systems. They are like the "traffic directors" of light. They help divide and manage light beams for various applications. Without them, many optical
