What is Soft Output Decoding?

Explains the difference between making "hard decisions" and "soft decisions" in digital communications detectors and decoders, and shows a simple example.

amazing content lain, thanks for this one it really cleared lot of my doubts

[@iain_explains]

Glad it was helpful!

[@chakib2378]

Thank you for still keeping this youtube channel alive ! I am still learning thanks to you

[@iain_explains]

I'm so glad that you're still finding the channel interesting. I plan to keep making videos for as long as I keep getting nice comments like yours from viewers who value the content. 😁

[@Official_VP]

Great Video!! Thanks alot! Can you make a video on methods(Maximum ratio combiner,Transmit beamforming,Alamouti code) in scenarios with more than two
Antennas?

[@iain_explains]

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

Hi Professor, would it be possible to do a PLL phase noise modeling video. I read many docs but still try to understand how to model the phase noise in frequency domain and how does that impact a baseband signal. Thank you!

[@iain_explains]

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

Thank You Professor for all the great coursework you put here .Your explaination is clear and precise. The different Sections and the Subsections are organised very well . Even for professional engineers like myself this is great reference , learning, revision material . Please keep adding more stuff ..Thank you !

[@iain_explains]

Thanks for your nice comment. I'm so glad you like the videos.

[@pitmaler4439]

Thanks, but what is now the disadvantage of s.d.? I assume there are hard decoders in the world, why? Does s.d need more storage for that soft-information? More computation effort?

[@iain_explains]

Yes, good point. It needs more storage and more computation effort - exactly as you say.

[@sepehrariaei8123]

Can you please make a video on Turbo Decoding and Coding Algorithms? I really need to learn it for my job and it is very hard to understand it.

[@iain_explains]

Thanks for the suggestion. It's on my "to do" list.

[@gadepalliabhilash7575]

Hello professor, Thanks for very clear explanation. Could you please make a video on Soft output Viterbi Algorithm(SOVA).

[@iain_explains]

Thanks for the suggestion. It's on my "to do" list.

[@stringstoparadise2392]

sir I have learnt soft decoding map criteria and all that but I have never learnt the way you explained in this video you are a rockstar of communication system...a big thanks sir 👍

[@iain_explains]

I'm so glad you liked the explanation.

[@plastilinovbly]

It was very clear and helpfull! Thank you:)

[@iain_explains]

Glad it was helpful!

[@beincheekym8]

thank you for the very clear video, great introduction to the concept of soft output decoding.

[@iain_explains]

Glad you liked it.

[@masoudata]

Very nice explanation of the concept. 👍

[@iain_explains]

Thanks. I'm glad you liked it.

[@renightmare1]

Beautiful explanation

[@iain_explains]

I'm glad you liked it.

[@tuongnguyen9391]

Does this soft output decoding stuff increase the complexity of the receiver which in turn make it take more time to decode ?

[@iain_explains]

Yes, soft output decoders are definitely higher complexity, but you still need to complete the decoding within the same time, otherwise delay would build up.

[@stephensu4371]

nice

[@iain_explains]

Thanks
