sir i am really grateful for this video ! this is a game changer , we were just introduced about it in college and just ignored .. your explanation made it look so easy 🙏 thanks a lot sir i am sharing these with all my mates , and also it would be really wonderful of you if you can cover more of LTE in the future i wish and pray for the success of your channel ! much much thanks from India

You are most welcome. OK, I'll think about a few more LTE based topics. Thanks for your feedback and the suggestion. And thanks for sharing with your mates.

Great explanation sir! I need a small clarification. When do we use rayleigh fading and rician fading. In other words, when do we consider the line of sight path and when do we ignore it?
@iain_explains
@iain_explains 3 жыл бұрын
Really the only thing that differentiates the paths is their Path Gain (and their delay of course, but in this case we are assuming that all the paths arrive within a timeframe that is much shorter than the transmitted modulated symbol duration). If there is one path (or a small number of paths) that have a much stronger gain than all the others, then the distribution will be Rician. Generally a LoS path has the characteristic of being significantly stronger than the other (reflected) paths. But it could also be the case that there is no LoS path, but there is a strong reflected path, that is significantly stronger than all the other reflected paths (perhaps it is bouncing off a metal wall for example). It's not a case of "considering" or "ignoring" the LoS path.

Many thanks for your clear and interesting presentations Iain, I hope you are making some money out of the mind blowingly banal adverts KZbin intersperses them with, you certainly are the shine-ola of the presentation 😁

Hello. Thank you for the good lecture. I have a question, I want to measure the Rician K-factor in the environment. What is the peak amplitude of the dominant signal? What is the unit of power of delayed signals measured by channel impulse response? Amplitude is in units and measured values are in RSSI (received strength signal indicator) dBm, but Rician is called Voltage Amplitude, which is confusing.

I'm not exactly sure what you are asking here, but don't forget that P=V^2/R, so Power is directly proportional to the square of the voltage.

Hi, thanks for the nice explanation. I’m wondering what is the distribution of the channel phase for the Rician fading channel?
@iain_explains

It's a uniform distribution.
