Advanced Digital Communication
This course provides participants with a comprehensive understanding of advanced digital communication techniques. It enables you to make design choices based solely on system requirements and constraints. The course covers advanced modulation techniques, fading channels and mitigation techniques, spread spectrum techniques, and performance analysis of Single and Multi-carrier receiver systems. Information Theoretic concepts along with CDMA and GSM system examples provide participants with a working knowledge of advanced digital communication systems.
