WebMay 10, 2016 · I want to send one bit x over a noisy channel, specifically, a binary symmetric channel with error probability p, where p = ( 1 − ϵ) / 2 and ϵ is small. In other words, the error probability is close to 1/2, so the capacity of the channel is small. The obvious method is to use a repetition code: repeat x many times. Webare permutations of each other, then the channel is called symmetric. For such a channel, we have that H(YjX= x) = cis constant for all x2Xand so H(YjX) = cas well, and so for any …
