COURSE CONTENT

This course will focus on tradeoffs in designing wireless systems, and show how to seamlessly move between both the circuit and system level in radio transceivers and other RF systems. We do this by looking at typical radio architectures, exploring the design tradeoffs, and simulating at both the circuit and system level. The course treats digitally coded signals in RF and IF components, and explores the compromises that are inherent in the design of a radio transceiver.

From the RF perspective, the need to minimize interference from nearby unwanted stronger signals and to allow detection of a desired signal in noise is critical. Avoiding corruption of other signals sharing the spectrum is equally critical. Achieving both together is not so simple! In wireless LAN for instance, we will see how tradeoffs made to solve one problem, like multipath reception, have placed tight constraints on other parts of the system, such as the linearity of the power amplifier.

We will interactively simulate a double super-heterodyne, dual-band radio receiver, a direct conversion receiver, and an I-Q modulator and transmitter, as well as multiple components. This provides the opportunity to explore 'what if?' scenarios.
