What is the capacity of binary symmetric channel?
The capacity of the binary symmetric channel is C = 1 − H(p) bits per transmission, and the capacity of the binary erasure channel is C = 1 − α bits per transmission.
What is cascaded channels?
(a) The transition from one generation to the next can be modelled as communication of information through a noisy channel. Thus, long waiting times can be modelled as a cascade of similar channels.
What is meant by binary symmetric channel?
Definition 1.1
The Binary Symmetric Channel has input and output alphabets equal to 0, 1. The probability that a received symbol is actually equal to the transmitted symbol is given by 1 − p, while the probability that they are not equal to each other is p, for some 0 ≤ p ≤ 1.
How to find the equivalent channel matrix when two BSC are connected in cascaded form?
First, we need to find the equivalent channel matrix: X = YI = (0.75*0.75) + (0.65*0.65) = 0.82 + 0.18 = 1.12 Next, we need to determine the overall channel capacity: C = X*P(x) + Y*P(y) = 1.12*0.65 + 1.12*0.75 = 0.86 Finally, we can determine the efficiency and redundancy: E = C/P(x) = 0.86/0.65 = 1.4 Efficiency is ...
