Introduces the theory behind OFDM signals. What are orthogonal functions? What is an OFDM symbol how is it generated and decoded. Slides at: github.com/irfanalii/youtube_...
Great clarity in explaining such a complicated subject - only possible with good knowledge, good experience and presentation skills. Thank you for the best presentations I have seen on the subject.
Hey Irfan.These videos are really very informative. You seem to be referring to videos on charging policies and QoS in your lectures but doesn't seem they are on your channel. Any chance of making them public if you have them handy. Again thanks a bunch for these videos!
If you use any type of modulation (e.g QPSK, 64QAM...) then which is the basis signal (raised cosine?). The way you proposed it here it is just a rectangular wave from [0, T] and therefore ISI exists (this is not useful) and also if you have a multipath channel there will be also ISI. I find this good as an introduction of how OFDM works but you skip many key facts.
Sir,
you are the only person I've ever seen who has elaborated on these things in this much detail in a very informative way.
Thank you.
This is the best OFDM explanation I’ve seen on TH-cam
man.. this is wonderful clarity of information. Thank you so much. God bless you
Thank you Sundaraman.
Arguably the best tutorial on LTE in TH-cam
BEST OFDM IMPLEMENTATION VIDEO.
BEST explanation on OFDM on the internet till date..
Irfan sahib this is the best explanation of OFDM on youtube as far as i saw, thank you so much.
The way you are explaining the concepts is excellent sir. Hats - off to you.
The best lecture on the TH-cam, thanks so much
No where I could find such a clear and easy explanation for beginners. Thank you so much sir
The way you explain things is just wonderful.
Excellent training Mr. Irfan. You have great way of making such complex topics in a very easy way.
Irfan, very good overview of the basics. Really enjoyed watching this. Thanks!
Excellent explanation on LTE!!
Thanks sir, excellent explanations..!!! The way of linking the math and graphs are really clear..

Extremely well explained. Very detailed.
thanks too much dear professor I really need these parts
excellent description with much details. Good job man
Dear Sir,
You have great knowledge and greater ability to put that knowledge in front of viewers
Great explanation, thank you!
finally easy to understand explanation of OFDM!
Excellent explanation! Thank you.
Highly recommended watch... waiting for my Bell to ring to get more video updates
From the best explanation i ve seen thnks so much
Excellent videos! The best I could find on TH-cam. It would be great if we could get the slides used.
This is frigging BRILLIANT !!!!!!
Beautiful explanation
You are a great teacher. Very unique teaching style.
Thank you very much Kobby. You made my day :-)
impressive Irfan
your videos are very easy to understand and concept-oriented . can you post a video on csfb and volte
Irfan - You're awesome! - I'm enjoying your lectures on LTE!....Do you have a set coming out for 5G?
All lte.. good sir
Thanks Sir , for making it easy to understand.
are you planning to cover for UL/SCFDMA any time soon ?
your tutorial is brief and effective; my headache is off now, pls pls dyu have a tutorial on Raylien fading?? if not, special request

Fantastic explanation - OFDM is no longer an abstract concept...
Lost it at functions. It's been too much time since I used functions in university
38:04 is the entire resource block allocated to one UE or the entire sub-frame ?
Hi, power of RE will amplitude of each cos signal( in your example was 1.4) ?
Hi sir, please make more videos on LTE
Super
u r too too good😀😀😀😀
Do scheduler assign single or two resource blocks to each user?
5ms preamble and only 66.67us symbol time? is it too much overhead?
my mistake. is 5us not 5ms.
Symbol? Or signal?
symbol
