The abstract below i s for both Part I and II:\n\nThe main benefit of OFDM is its ability to co pe with severe multipath channel conditions without the need for complex e qualization filters. How does it accomplish this? The short answer: by "di viding and conquering." It partitions a high-data-rate signal into smaller low-data-rate signals so that the data can be sent over many low-rate sub -channels.\n\nThe Time/Frequency relationships are presented with a figure that facilitates a straightforward understanding of the OFDM partitioning process. We emphasize the important role of the cyclic prefix (CP). We sh ow how it allows us to change linear convolution into circular convolution \, thereby purging any transients\, which helps to maintain waveform ortho gonality at the receiver.\n\nOFDM waveform synthesis is covered in detail. Also\, the spectral properties of Real and Imaginary signals are reviewed . We further consider the peak-to-average power ratio (PAPR) in OFDM\, and how the desire for small PAPR has given rise to a special variant of OFDM called single-carrier OFDM (SC-OFDM). Finally\, we illustrate application s of this elegant technology in standards such as 802.11 and LTE.\n\nSpeak er(s): Dr. Bernie Sklar\, \n\nAgenda: \n6:30-6:45 (PST) PM Virtual Social\ n\n6:45-8:15 (PST) PM Presentation\n\n8:15-8:30 (PST) PM Q&A\n\nThousand O aks\, California\, United States\, Virtual: https://events.vtools.ieee.org /m/262902 LOCATION:Thousand Oaks\, California\, United States\, Virtual: https://even ts.vtools.ieee.org/m/262902 ORGANIZER:vslin@ieee.org SEQUENCE:15 SUMMARY:IEEE COMSOC CHAPTER TECHNICAL TALK - The ABCs of Orthogonal Frequen cy Division Multiplexing (OFDM) Part I URL;VALUE=URI:https://events.vtools.ieee.org/m/262902 X-ALT-DESC:Description: <br /><p><strong>This is Part I of a Two Part Talk on OFDM.
