Reference Encoding of Correlated Digital Sources
J.W. Mark, P. Dasiewicz · IRE Transactions on Communications Systems · 1978
A reference code, with an associated bound on the code rate, for the encoding of correlated digital sources is introduced. The reference code is adaptive and simple to implement. Image coding results obtained using concatenated trellis and reference encoding are presented. For the images studied, the reference code attains an average code rate of approximately 0.64 bits/bit, or a reduction in information rate of approximately 36%.
