Named after Claude Shannon, the source coding theorem shows that, in the limit, as the length of a stream of independent and identically-distributed random variable (i.i.d.) data tends to infinity, it is impossible to compress such data such that the code rate (average number of bits per symbol) is less than the ...

Definition (Rate of a Code). An [n,k]2 code has rate k/n. For every channel, there exists a number called its capacity. C ∈ (0,1) that measures the reliability ...
