[b]Description[/b]

OFDM is a special form of multicarrier RF transmission involving orthogonal subcarriers or tones, designed to mitigate the delay spread caused by multipath signal propagation and other forms of interference. It has been widely adopted in wireless and wireline standards, including Wi-Fi, 4G/5G, DSL, HomePlug, and more recently, cable (DOCSIS 3.1/4.0). This course covers the foundational principles OFDM/OFDMA and the underlying technologies of broadband systems. It is intended for practicing engineers, researchers, and students. Learning OutcomesOFDM principles and analysisOFDM metrics: FFT size, power spectral density, cyclic prefix, peak-to-average power ratioOFDM transceiver design, sub carrier synchronization, and error performanceOFDM performance enhancements using multi-user OFDMAFast Fourier Transform (FFT) and inverse FFT (IFFT)About the InstructorThe instructor was a technical editor for the IEEE Wireless Communications Magazine for 10 years and has also guest edited for the IEEE Communications Magazine (2 issues) and the IEEE Journal on Selected Areas on Communications. His IEEE online tutorials were sponsored 8 times by industry. His research has appeared in the IEEE Spectrum and he received 2 IEEE best paper awards. He was invited by the National Science Foundation to participate in a workshop on Residential Broadband and received the National Association of Broadcasters Technology Innovation Award. He has also served as an IEEE Communications Society Distinguished Lecturer with 10 invited lectures worldwide as well as an expert witness.
