Noisy channel

Python creates certain number words that come as a parameter, then sends the same word many times to see the probability of success or failure

In the shell script I do repetitions of words of a certain length, also i change the length of the word and the probability of 0 and 1, then in an awk script I can get the standard deviation and the averange, and send this data to the final file and process the data.

Shell script

In awk script I get the average and standard deviation
AWK script

With gnuplot I produce a graph to know what happened in the experiment.

And some plots that can help us to underestand the results.

q0 = 0.1
q1 = 0.1

 After I implemented more functions to analyze probabilities of 0 and 1 (q0, q1), and also compute the standard deviation.

While the length of the chain grows the probability of success is weakened and if the frequency of 0 is high but the probability of success to 0 It is not as high like the probability of 1 then while the frequencies of 0 going up so these will lose the success rate because In longer words are more failures.

  1. Your readers would probably appreciate having the figure legends and the code commentary in English as well ;) 5 pts for the code, and in the report, having written it in English compensates the spelling errors and it's also worth 5 pts.
