A possible coding scheme for this channel with two code words of length 3 is to encode message a1 as 000 and a2 as 111. With this coding scheme, we can consider the combination of

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 Symmetric Channel (BSC) • BSC is the simplest model for information transmission via a discrete channel (channel is ideal, no amplitude and phase distortion, only distortion is due to AWGN): s X1 X0 P(X1) P(X0) Y1 Y0 P(Y0 X0)
