Beamforming in 5G Cellular Systems: A TutorialStatus: Available Now
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.

Timing Synchronization in Software Defined Radios (SDR) (2020)Status: Available Now
A Software Defined Radio (SDR) merges the two fields of digital communication and digital signal processing into an efficient implementation of transmitters and receivers. One outcome of this combination is an interesting perspective on how timing synchronization is performed in digital communication receivers. This session will explain the timing synchronization problem in both time and frequency domains and then discuss in detail a timing locked loop consisting of timing error detectors, loop filter, interpolation and interpolation control. Insights into the relation of timing synchronization with general receiver design will also be presented.
