Mobile Radio and Cellular PCS: Digital Design Techniques

Course Summary

This course provides participants with a foundation in the elements comprising the radio interface (physical layer) of digital mobile wireless communication systems, as well as descriptions of current and future systems. It includes the basic building blocks of digital mobile cellular systems, such as multipath channels, modulation, coding, equalization, diversity, and multiple access techniques. This course also combines theory and real-life examples to provide participants with a complete foundation in digital communication techniques and their effects on RF Circuit Design, to help close the gap between traditional RF engineering design and the needs of modern digital mobile radio systems.
