The abstract below is for both Part I and II:\n\nThe main benefit of OFDM is its ability to c ope with severe multipath channel conditions without the need for complex equalization filters. How does it accomplish this? The short answer: by "d ividing and conquering." It partitions a high-data-rate signal into smalle r low-data-rate signals so that the data can be sent over many low-rate su b-channels.\n\nThe Time/Frequency relationships are presented with a figur e that facilitates a straightforward understanding of the OFDM partitionin g process. We emphasize the important role of the cyclic prefix (CP). We s how how it allows us to change linear convolution into circular convolutio n\, thereby purging any transients\, which helps to maintain waveform orth ogonality at the receiver.\n\nOFDM waveform synthesis is covered in detail . Also\, the spectral properties of Real and Imaginary signals are reviewe d. We further consider the peak-to-average power ratio (PAPR) in OFDM\, an d how the desire for small PAPR has given rise to a special variant of OFD M called single-carrier OFDM (SC-OFDM). Finally\, we illustrate applicatio ns of this elegant technology in standards such as 802.11 and LTE.\n\nSpea ker(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 Oaks\, California\, United States\, Virtual: https://events.vtools.ieee.or g/m/263739 LOCATION:Thousand Oaks\, California\, United States\, Virtual: https://even ts.vtools.ieee.org/m/263739 ORGANIZER:vslin@ieee.org SEQUENCE:6 SUMMARY:IEEE COMSOC CHAPTER TECHNICAL TALK - The ABCs of Orthogonal Frequen cy Division Multiplexing (OFDM) Part II URL;VALUE=URI:https://events.vtools.ieee.org/m/263739 X-ALT-DESC:Description: <br /><p><strong>This is Part II of a Two Part Talk on OFDM.
