Hi there! I love your videos but I feel like I'm missing something very fundamental... you see, I'm trying to understand all that goes on with 802.11 at the physical, RF layer. At a very basic level, I understand how modulation works, and I know what the purpose of phase modulation is... but I'm not entirely sure how it is accomplished. It's typically depicted on illustrations as the signal being "cut off" mid-phase, or having two signals overlapping... but my guess is that's not what really is happening? Does phase modulation involve a small bit of frequency modulation? Like, how is phase generally communicated by a wireless transceiver? Sorry if this question doesn't make much sense... I'm just so confused. Also, in the context of OFDM, I'm confused as to what the "sidelobes" represent on subcarriers, as well as the relationship between the subcarrier width and the symbol length (why are these always inverse?). Could you explain some of that?

These videos should help: "What is a Constellation Diagram?" ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-kfJeL4LQ43s.html and "OFDM Waveforms" ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-F6B4Kyj2rLw.html And make sure you check out my webpage that has a categorised listing of all the videos on my channel: iaincollings.com

What is the difference between "regular" frequency (f) and angular frequency (ω)? Regular or linear frequency (f), counts the number of complete oscillations or rotations in a given period of time. Its units are therefore cycles per second (cps), also called hertz (Hz). Angular frequency (ω), also known as radial or circular frequency, measures angular displacement per unit time. Its units are therefore degrees (or radians) per second.

Yes, that's right. As I mentioned in the video, ω=2pi f

If it was some tiktoker eating their own sxit, they would have got so many views but for someone who is providing knowledgeable content and putting so much effort for us, views in 500s tell what kind of society we are living in nowadays. Thanks sir. I have learnt so many concepts from u.❤️👏

The interface of Entertainment and Education is a delicate balance. As you've seen, I prefer to focus on the fundamental understanding of ideas and topics. I know it gets fewer views than a more entertainment-aligned presentation, so it's great to hear from people like you, who really appreciate it. I'm so glad you like the channel.
