For uniquely decipherable codes, Shannon [30] found the lower bounds for the arithmetic mean by using his entropy. A coding theorem analogous to Shannon’s noiseless coding theorem has been established by Campbell [6], in terms of Renyi’s entropy [29]: Hα (P) = 1 1−α log D N i=1 pα i,α>0(= 1).

STATEMENT OF THE THEOREM Suppose Xi is an i.i.d. information source with entropy rate H (X). Suppose R > H (X). Then there exists a reliable compression scheme of rate R for the source. Conversely, if R < H (X) then any compression scheme will not be reliable.

In 1935 and 1936, Schrödinger published a two-part article in the Proceedings of the Cambridge Philosophical Society in which he discussed and extended a remarkable argument by Einstein, Podolsky, and Rosen.
