WebThe analog of the binary symmetric channel in which some bits are lost (rather than corrupted) is the binary erasure channel. In this channel, a fraction α of the bits are erased. The receiver knows which bits have been erased. The binary erasure channel has two inputs and three outputs as shown in Fig. 5. We calculate the capacity of the ... 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 …

Webbinary entropy function. If either h 6= 0 or 1 the maximizing value in (17) is unique, denoted as ;h(which can be obtained by numerical optimization). In particular, ;0 = 0 in this case. When h= 0 and >1, there are two maximizing values which are symmetric around 0, with the positive value being denoted as + ;0 6= 0 . From results in [12], if ... WebThis states that the capacity of the binary symmetric channel is precisely 1 H(p). We will need the notion of the Hamming distance.
