Course Syllabus
Module 1: Introduction and History of Cellular Communication Systems
Cellular Communication, First to Second Generation (1G to 2G), Third Generation System (3G), Fourth Generation System, (4G), Future Cellular System.
Module 2: Principles of Wireless Communication Theory
How can we represent information into a binary format? How can information be transferred? , How does wireless digital MODEM work? How can high-rate data be delivered reliably? How can many users access simultaneously?
Practice: 1. Describe the location of where you experienced the largest number of Neighbor Base Stations, and how many were there. In addition, describe the PCI, RSSI, RSRP, RSRQ, RSSNR, ASU, and CQI values measured.
Module 3: Wireless Channels
Large scale path loss – Path loss models: Free Space and Two-Ray models -Link Budget design – Small scale fading- Parameters of mobile multipath channels – Time dispersion parameters-Coherence bandwidth – Doppler spread & Coherence time, fading due to Multipath time delay spread – flat fading – frequency selective fading – Fading due to Doppler spread – fast fading – slow fading.
