How Does a Doppler Shift Affect Digital Communications?

[@vikramgaud6276]

Thank you, sir, for one more video. In each video, you try to explain the concept from the basic level. Here also, you covered each line of your explanation, which is the good part.

I'm glad you like the approach I take in my videos.

Good content as always Iain, good start to my morning :)

That's great to hear. I'm glad you like the channel.

Great explanation of how doppler affects a signal! What would be the best way to simulate a Doppler shift on an OFDM signal?

[@iain_explains]

Great question. I've already recorded a video on the effect of the sinc function on OFDM, but I haven't had time to edit and upload it yet. Keep and eye out over the next couple of weeks.

question：is match filtering the same as down conversion mentioned in the video?

[@maazawan7629]

Beautiful explanation sir!
However to cater for doppler shift in a single carrier FSK system, we keep our receiver filter bandwidth greater than the channel BW+max doppler shift in frequency due to relative motion of the communicating nodes.
That also tends to reduce the SNR because we now need a wider BW of receive filter leading to an increased noise floor.
However your intuitive and picture perfect theoretical explanation really nailed it.
Keep making these videos.
Best Regards

Thanks for the video, sir. Could you do a video on the introduction to space-time coding？

[@iain_explains]

Thanks for the topic suggestion. I've added it to my "to do" list.

Can you do a video on the concept of "Age-of-information (AoI)" ?

[@iain_explains]

Thanks for the suggestion. I've put it on my "to do" list.
