Shannon theorem for noisy channel

WebbCHANNEL CODING THEOREM: T he noisy-channel coding theorem (sometimes Shannon's theorem), establishes that for any given degree of noise contamination of a communication channel, it is possible to communicate discrete data (digital information) nearly error-free up to a computable maximum rate through the channel. This result was … WebbIn this case, Shannon’s theorem says precisely what the capacity is. It is 1 H(p) where H(p) is the entropy of one bit of our source, i.e., H(p) = plog 2p (1 p)log 2(1 p).
