Qasim Chaudhari writes about wireless communications and signal processing at https://wirelesspi.com. After obtaining a PhD in Electrical Engineering from Texas A&M University, he has mostly worked on DSP algorithms development for real world demonstrations of wireless systems such as a MIMO-OFDM testbed, low-SNR receiver and phase of arrival based localization. His current venture is experimentation on extracting the range of a wireless device from the communication signal for some particular modulation schemes.
Cellular networks have to minimize the interference among network users in addition to maximizing their individual data rates. From this perspective, beamforming is the core technology behind the design of the 5G physical layer. In this tutorial, we start from the basic signals and build the fundamental ideas on which physical and virtual beamforming methodologies are based. We will explore how its integration with massive MIMO leads to a simple yet efficient system. No prior DSP knowledge is required to understand the concepts.
