(Binary Erasure Cannel) Suppose that Γ is the binary erasure channel (BEC), the input probabilities of 0 and 1 are ? and ?̅, and the probability of sending source symbols correctly is ?. Assume ?=0.6 and ?=0.7. Please compute the system entropies H(A), H(B), H(A|B), H(B|A), and H(A,B).
We have given input probability of 0 and 1 are ? and ?̅
Where, ? = 0.6
As we know ? + ?̅ = 1, So, ?̅ = 1 – 0.6 = 0.4
?̅ = 0.4
The probability of sending source symbols correctly is P and probability of sending source symbols with error is P
Where, P = 0.7, 1 - P = 0.3
