Class Cooperative Wireless Systems

Wireless Cooperative Systems is a first-year doctoral unit with a foundational chapter that examines systems, technologies, and user-centric communication paradigms. It equips students with knowledge of next-generation networks to study low-cost, robust solutions that extend wireless access, linking architectures, techniques, and services in cooperative wireless systems. The unit introduces advanced technologies—NOMA, AF/DF relays, and UAV cooperative communications—and essential tools for large-scale systems study, including graph theory, information-dissemination algorithms, distributed optimization, cognitive radio, and SWIPT-based systems, preparing students to contribute to research in advanced wireless technologies. It also spans fundamentals (WiMAX, VANET, 4G LTE/LTE-Advanced), simulation of detection methods in MATLAB/Python, dedicated UAV modules, spectrum-optimization via NOMA and cognitive radio, SWIPT and optimization topics, and group projects.

Classes are expository. The active participation of students in the teaching process is encouraged through questions that stimulate interest about the subject. When appropriate, the presentation of the material is preceded by the study of concrete situations that students are familiar with. Some topics arise from the analysis of problems whose resolution make the concepts to be studied natural and straightforward. The material is always illustrated with examples and counter-examples. Some problems are left for students to analyze and solve. The assessment consists of: - homework done throughout the semester (30%); - final project (70%).
