英国威格斯PEEK 450PF详解：
The solutions to these solved special cases suggest acoding technique for the general model [15, 16]. The idea isthis. Each encoder first its obser-vation as insingle-user rate-distortion theory. The processesare then losslessly communicated to the decoder using the binningscheme of Cover [17].
The decoder uses the processes to produce the desiredestimates. The set of rate-distortion vectors that can beachieved using this scheme is described in Section 3. This inner bound to the rate-distortion region is tight in all of the special cases listed above except that of K¨orner and Marton [9]. Indeed,the K¨orner-Marton problem seems to require a custom coding technique that relies on theproblem’s unique structure. This suggests that themultiterminal
source-coding problem may not have a classical single-lettersolution.
