This course covers the foundational principles OFDM/OFDMA
and the underlying technologies of broadband wireless systems. It is intended for practicing engineers, researchers, and students. Wireless access has evolved rapidly in the last two decades and has become the dominant medium for network connectivity in fixed and mobile applications. It started with cellular (1990), followed by Wi-Fi (2000), and these systems are evolving into an ecosystem involving 4G/5G and Wi-Fi (802.11n/ac/ax). The first part of the course focuses on the principles of Orthogonal Frequency Division Multiplexing (OFDM), which forms the basis of 4G/5G/Wi-Fi systems. In addition to its benefits, key OFDM metrics are discussed. OFDM enhancements using multi-antenna MIMO and multi-user OFDMA are then described. An overview of LTE and Wi-Fi is provided next, together with a comparative assessment of the strengths and weaknesses of these systems. Additionally, the physical layers, MAC layers, and network architectures are studied and analyzed. The course concludes with some examples of real-world wireless deployments in indoor and outdoor settings. Upon completion of this course, the student will have acquired fundamental knowledge of OFDM and 4G/5G/Wi-Fi systems, including practical considerations in OFDM implementation and enhancement, and tools to apply OFDM in next-generation wireless networks. Participants will also work on a Matlab project.
