Short description

The course gives a general overview of radio systems and their components. Therefore the focus is on the analogue parts of the system with their non-idealities. Based on the physical functionality of the various building blocks of a modern radio system parameters are derived, which allow the consideration of their influence on the overall system performance.

Tutorial

The tutorial is based on the professional simulation software SystemVue from Keysight (formerly Agilent) Technologies. SystemVue is a focused electronic design automation (EDA) environment for electronic system-level (ESL) design. It enables system architects and algorithm developers to innovate the physical layer (PHY) of wireless and communications systems and provides unique value to RF and DSP implementation. As a dedicated platform for ESL design and signal processing realization, SystemVue replaces general-purpose digital, analog, and math environments.

The tutorial begins with system design and simulation of homodyne and heterodyne receivers followed by QPSK transmitter and concludes with FMCW radar design.  The system design aspect is greatly simplified in Systemvue as components can be simply dragged and dropped from libraries (e.g. RF design kit, algorithm design, RADAR parts). Additionally, several commercially available component data sheets are also inbuilt in the software which will help students towards fast-track RF application learning. The simulation aspect covers system parameters like gain, noise figure, dynamic range, 2nd and 3rd order nonlinearities, eye diagram etc. Thus enabling students in understanding the key concepts in system design and imparting a better understanding of concepts covered during the lecture.
