OFDM Tutorial Series: OFDM Fundamentals

The OFDM Tutorial Series goes in depth into the theory and implementation of OFDM wireless communication systems. Starting with the treatment of multipath fading channels, OFDM is introduced as a bandwidth efficient robust communication system for multipath fading channels. Using IEEE 802.11a as a basis, a full OFDM system is described in both theory and implementation. In particular, detailed description of acquisition including packet detection, timing synchronization, carrier frequency offset estimation and correction and channel estimation and equalization is presented along with implementation details.

Excellent!

Just an amazing series. Thank you, sir. I really appreciate the work and time you have put in to make this series Dr. Sasan Ardalan.

One of the best explanation ever on this topic!

[@tihihoang]

woww thank you so much ❤ 20:00 is exactly what I found for many days T.T like, I understand the IFFT freq/time domain, sum of the signals (I mean the X_k * exp(..) signals)... concept, but I kept wondering how to map these before-IFFT signals map to frequencies of the subcarriers (like 0, 30, 60,... kHz), because the frequency of IFFT and (0,30,60,... kHz) are totally different ^^ now you saved my days ❤❤ Thanks a lot

Excellent presentation, many thanks!

[@tasneemassaf3610]

Perfect explanation

[@thabangntema620]

What is the relationship between modulation scheme and fft length?

[@nikosapostolakis7895]

At 18:42, why the FFT length is equal to the total number of subcarriers?

[@asdrty258]

Can be embedded any spyer sub carrier? #geohotz
