Channel
Instructions
    Quick theory overview:
  • For the \( BEC(\epsilon) \) memoryless channel, the transition probability is given by:

    \( p({y}|{x}) = \begin{cases} \epsilon^{w_e(y)}(1-\epsilon)^{n-w_e(y)} & \text{if} \ {x} \ \text{and} \ {y} \ \text{are compatible} \\ 0 & \text{otherwise} \end{cases}\)


    Procedure:
  • There are two exercises in this part of the experiment.
  • In the first exercise, you are given a codeword, and you have to identify what are the possible outputs of the Binary Erasure Channel.
  • After selecting the output vectors accordingly, click on the Submit button. Observations will be displayed accordingly.
  • Only after you have selected all the correct output vectors will the Next button appear to go to the next exercise.
  • Click on the Reset button to reset all your selected choices and restart the exercise.
  • For the next exercise you must enter the probability of receiving each of the previously selected output vectors, from the input codeword, in the boxes given.
  • Once you have entered all the values, click on the Submit button. Observations will be displayed accordingly.
  • Click on the Previous button to go back to the first exercise or the Reset button to reset all your selected choices and restart the experiment from the first exercise.

A codeword needs to be sent through a Binary Symmetric Channel \( (BEC(\epsilon)) \) as shown below. Select the possible vectors that could be received through this channel.
