COURSE DESCRIPTION
This course will cover a detailed design view of various physical-layer building blocks that are essential for building a complete digital transceiver for wireless communications. The building blocks include modulation, demodulation, carrier frequency and phase offset compensation, timing synchronization, and equalization, with particular emphasis on discrete-time (digital) realizations. In addition to covering fundamental concepts, the course content will also present techniques and algorithms typically deployed for efficient system-level operation of the digital transceivers. The theoretical coverage in the class will be accompanied by detailed computer assignments, that will progressively lead up to the students implementing their own software-defined baseband digital wireless transceivers. Using software-defined radios (USRPs) available in the lab, the students will be required to demonstrate the working of their implementation with real-world wireless links.
