Explore the fundamentals of Orthogonal Frequency Division Multiplexing (OFDM) in this comprehensive 1.5-hour video series. Delve into key concepts such as OFDM waveforms, the relationship between OFDM and the Discrete Fourier Transform (DFT), and the importance of cyclic prefix in OFDM systems. Learn how OFDM effectively overcomes Inter-Symbol Interference (ISI) and understand the concept of Peak-to-Average Power Ratio (PAPR) and its connection to OFDM. Discover the similarities between OFDM and xDSL (DMT) technologies, and gain insights into the relationships between throughput, bandwidth, and data rate. Examine the correlation between OFDM subcarrier spacing and time samples, and explore the principles of MIMO OFDM. This video series serves as an excellent resource for those interested in digital communications, complementing related playlists on Communication System Fundamentals, Digital Communications Receivers, and Multiple Access in Digital Communication Networks.
