OFDM - Orthogonal Frequency Division Multiplexing

Please support my channel by becoming a Sunny Classroom member. Your support is much appreciated.

Today I will talk about variation of FDM: Orthogonal Frequency Division Multiplexing, or OFDM. OFDM is being used for many of the latest wireless and telecommunications standards, such as Wi-Fi 802.11ac, both 4G LTE and 5G cellular technologies, WiMAX, and many more. It is a very popular multiplexing technology.
So what is big deal of the OFDM? Why does it have many advantages over FDM?

Fast, simple and effective explanation. His teaching method is perfect. His spoken English with pauses makes it easy to understand. You have gained a follower from Brazil.

Is this magic? You just explained the same concept my professor explained, but he took an hour and you took only 4 mins. I am thoroughly impressed.

[sachureedas]

Are you kidding me!! Why has no one ever thought of explaining this topic like this. So easy to

[perfectpakka]

God-Level Definition of OFDM! Helped me a lot for my exams... Thank you, sir... Love from India

Please keep on delivering your great lecture on wireless communication! thank you.

[varadybalint]

Oh my god you have just explaimed it better in 3 and a half minutes than our professor in a whole semester

The concept of Orthogonality, (avoiding interference by other signals nulling) was the best I have seen so far. So easy to understand. Thank you!

[creativeworx]

I have a Wireless Networks today, and I have been struggling to understand how OFDM, your video got me strait to the point. Thank you so much😊

[sairohith]

How can someone unlike this wonderful lecture on OFDM :< ....A very insightful and clear-cut explanation of OFDM has been provided, I loved it ! Thank you :)

[magedrefat]

The best video I have watched regarding FDM and OFDM. I really appreciate your efforts :-)

[riturajsinghrawat]

The concept you started at 03:00 is by far the easiest explanation every other teacher could not achieved.

[alexdelarge]

after ten years of university, i finally understood orthogonal signals with a 4 minutes video. you're great!

[geethikasrimuktha]

I'm disappointed that there is only one like button for this video. It was precise and so easy to understand. Thank you very much!

[shivamkumarsingh]

The best explanation some gave till now. Thanks!

[wildarguelles]

Holy Thank you! I have been searching for an easy lectures like this!

[sanjeevKumar-eghp]

one of the best videos on OFDM
explained it so beautifully that its impossible not to understand
Thank you so much sir for sharing your knowledge in such an awesome manner

[randomgamerbuddy]

The way you explain this topic is brilliant. Hoping to see more of your lectures

Going in for a Verizon interview, and haven't been in tech for over a decade. I'm honestly trying to find jobs that can satisfy my level of tech knowledge without a degree. As an amateur radio operator, thanks for this. You just got a subscriber!

For the first time, I understood what is meant by orthogonal... beautifully explained.

[maalinee]

such a perfect and crisp explanation. Many research papers and video lectures yet fail to explain how the subcarriers are orthogonal to each other.
