Consider a binary input Q-ary output discrete memory less channe Consider a binary input Q-ary output discrete memory less channel. The channel is said to be symmetric if rite channel transition probability p(j|i) satisfies the condition: p(j|0) = p(Q– 1 –j|1), j = 0,1,…,Q – 1 suppose that the channel input symbols 0 and 1 […]

Consider a digital communication system that uses a repetition c Consider a digital communication system that uses a repetition code for the channel encoding/decoding. In particular, each transmission is repeated times, where n = 2m + 1 is an odd integer. The decoder operates as follows, if in a block of n received hits, the […]
