Shannon's channel coding theorem
WebbShannon's channel coding theorem states that "the error rate of data transmitted over a bandwidth limited noisy channel can be reduced to an arbitrary small amount if the information rate is lower than the channel capacity." This theorem is the basis for error correcting codes using which we can achieve error-free transmission. WebbTheorem(Shannon’sTheorem) For every channel and threshold ˝, there exists a code with rate R > C ˝that reliably transmits over this channel, where C is the capacity of the …

In this case, the rate R is the number of bits produced in the source per … Webband ergodic channels, the classical Shannon separation theorem enables separate design of source and channel codes and guarantees optimal performance. For generalized communication systems, we show that different end-to-end distortion metrics lead to different conclusions about separation optimality even for the same source and channel …
