Magic Man!
great and helpful, hope you're doing well.
Thanks for the kind words - I have created 200 videos covering digital comms. Will upload more if I get time.
If you attach the state machine implemented in the last video and replace "0 1 2 3" with "00 01 10 11", this diagram will make more sense.
thank you so much~!
thanks!
Voila :))))))))
What is omega of p
I guess it is the entropy function
The entropy function is H(w) = w log (1/w) + v log (1/ v), where v is 1-w. en.wikipedia.org/wiki/Binary_entropy_function
Is there an explanation in French
Harika. Amazing. PogChamp
Could you create a tutorial on using Hamming encoding/decoding? Specifically using the table to determine parity bits and error detection/correction. I searched for several hours, watching various hardly understandable videos before finding your channel on the Viterbi Algorithm in practice. Thank you.
Clear and concise, thank you!
Please post more videos , you made me understand very difficult concepts underlying the phasor simulations. Please put more videos directed at communication and signals. Many thanks.great work !
thank you sir. now i confuse about 2D viterbi decoding, can you show me for 2D 3x3 matrix?
Thank you mister really was usefull !
where is the next video? anyone please tell me. send me the link
great explanation
why do we give two zero bits at the end ? is it an ending delimiter ? because at the start also the state was 00
Because the encoder is flushed back to the all-zero state.
to departure back to the original
awesome but why cliffhanger? I want to listen further
thanks
I am watching this high at 2 AM and am just blown away by your conveying this ^^ thx
second part?
perfect thanks a million
Really you have a magic pedagogique methodology. you are one of the best teacher i've ever seen. thank you so much. that's what we call art of sharing knowledge.
simple, quick and well explained thank u so much
tks bro!
very easy to understand
Excellent video... U r d best wen compare with my lecturers
whats next video ?, i think its not finish.
after 01 in the trellis, you put another 01 and 11 in the received codeword, what is that, i thought its only 5 bit, what is the another 2 bit 01 and 11? answ: ah its another input to get 00, so you must put 2 more bits to get 00 back. [ solved ] thank you.
really it was awesome!
Very easy to understand
thank you for saving my life
amazing man. you are awesome (y)
Amazing, thanks!
that was easy to understand, thanks!
