WebThe channel capacity theorem also holds for continuous valued channels, which are very important in a number of practical scenarios, e.g., in wireless communication. But before … WebThe binary symmetric channel (BSC) with crossover probability p, shown in Fig. 6, models a simple channel with a binary input and a binary output which generally conveys its input faithfully, but with probability p flips the input. Formally, the BSC has input and output alphabets χ = = {0,1} and Sign in to download full-size image FIGURE 6.
