Software Defined Digital Radio Communications

Catalog description

Learn the principles and practices of how to engineer and implement software digital radio signal processing systems. Technology advances have brought us into the age of completely programmable full radio systems on a chip. ADC/DAC and high speed low power digital circuitry advances allow engineers to utilize digital signal processing techniques at RF and IF frequencies. By end of course students will understand how to statistically simulate receive and transmit fundamental digital radio modulations utilizing Matlab. As long as it is available by the time of the course and students/RIT can obtain equipment, exercises will be planned to implement some algorithms on a low cost educational digital radio kit (Analog Devices Educational Pluto Radio). Topics covered: OFDM, QAM, I/Q demod/mod, IF frequencies, encryption, channel interleavers, OSI Networking Layers 1 and 2. How to use iterative and non-iterative forward error correction (FEC) schemes. Efficient and proper utilization of RF spectrum, synchronization, radio channel equalization, understanding practical receive and transmit limitations, multipath channel models and an introduction to fixed point signal processing. The course will require much outside of class programming.
