Modulation & QAM Basics

This Video Explains QAM & Basic Modulation used in 5G, 4G, 3G, 802.11a/b/g/n/ac, Cable systems and many other forms of digital communications systems.

Thank you for this great video!

Very interesting, thank you Alan 💛

Great video for explaining the basics, doing a report on 802.11ax modulation and coding schemes and you managed to condense about 5 hours of reading into a short video. Thank you very much.

Excellent..Thanks a lot.

[@Darieee]

thanks a lot!! this is very clear now .. it took me about 4 years of loose searching to finally understand what happens with wi-fi ❤️

[@dmitriicheronko7101]

Thank you! The best explanation on KZbin!

[@lukashlupo5154]

Excellent lecture. Al the years I didnt understand this concept well

[@q1chen]

Super clean explanation. Thank you!

[@benjamincarter3608]

Great video. That helped me a lot. Very informative

[@slapweight7522]

great video, I finally understand whats happening! I think at 4:00 you accidently switched the phases of 1001 and 0100, right?

[@torcher5023]

1:27 how do you measure signal's phase after receiving?

[@jamesmcjamesington631]

Wasnt 2048 and 4096 used at the time of release of this video? How crazy is that compared to 256 qam?

[@steliospapadopoulos4589]

what about spatial streams have different received power?

[@ivanrados2443]

How to calculate the capacity of a link that uses QAM modulation. Is there a formula for the calculation?

[@murvindrake9862]

The amplitude is the length of the line, so it's neither 25 or 75.

[@MikolajKaminski]

3:57 wrong phase

[@ralfderwerwurm6960]

exactly!
