DESCRIPTION:For more information visit:\nhttps://www.crowdsupply.com/teardown/portland-2025/long-talk/the-unreasonable-effectiveness-of-the-fourier-transform\n\n---\n\nA good number of terrestrial high-bandwidth radio technologies (and even\, increasingly\, over wires!) seem to have converged on one air interface -- OFDM\, or Orthogonal Frequency Division Multiplexing.  As recently as 15 years ago\, there were no US cell phones that used an OFDM-derived air interface\; now\, no US cell phones do *not*!  Why is OFDM so popular -- and\, for that matter\, what even is OFDM?  We'll explore how OFDM works\, and how it neatly solves an enormous number of radio reliability\, efficiency\, and performance problems all with one computationally efficient algorithm: the Fast Fourier Transform.\n---\n\nFor more information about Teardown 2025 events\, please visit:\nhttps://www.crowdsupply.com/teardown/portland-2025\n
