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.

[@puneethprahalad7386]

[@pawansingh-ub2ej]

Beautiful explanation

[@UTMadMan]

Great explanation, thank you!

[@mustafasheik5726]

impressive Irfan

[@santhoshreddygogula2768]

your videos are very easy to understand and concept-oriented . can you post a video on csfb and volte

[@simranjitsingh4935]

38:04 is the entire resource block allocated to one UE or the entire sub-frame ?

[@ar_rahman_90]

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!

[@tejas_bodhe]

All lte.. good sir

[@mfaliali]

Thanks Sir , for making it easy to understand.
are you planning to cover for UL/SCFDMA any time soon ?

[@jewelossom8358]

your tutorial is brief and effective; my headache is off now, pls pls dyu have a tutorial on Raylien fading?? if not, special request

[@buthlezi3405]

Fantastic explanation - OFDM is no longer an abstract concept...

[@AnteBrkic]

Symbol? Or signal?

[@flintthuang]

symbol

[@chamankapoor7610]

Hi sir, please make more videos on LTE

[@ramrana1104]

Super

[@yernatsaduakas4168]

Hi, power of RE will amplitude of each cos signal( in your example was 1.4) ?

[@NoItsNotMe409]

Do scheduler assign single or two resource blocks to each user?

[@flintthuang]

5ms preamble and only 66.67us symbol time? is it too much overhead?

[@flintthuang]

my mistake. is 5us not 5ms.

[@hailsatyr]

Lost it at functions. It's been too much time since I used functions in university

[@grjesus9979]

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.
