Websimplify our analysis, we have restricted ourselves for the moment to binary discrete memoryless channels. For simpliﬁcation of the exposition, in this paper we will exclusively focus on two special cases: the binary symmetric channel (BSC) and the Z-channel (ZC). For results on general binary channels we refer to [5]. Note that while ... WebOct 28, 2024 · A DMC is defined to be symmetric, if the set of outputs can be partitioned into subsets in such a way that for each subset the matrix of transition probability has the property that each row is a permutation of each other row and each column is a permutation of each other column. DMC = discrete memoryless channel. Share. Cite.

Webreliability function of the channel). In particular, we prove that the “random coding exponent” is the true value of the channel reliability for codes rate in some interval immediately below the critical rate of the channel. An analogous result is obtained for the Gaussian channel.
