Achievable rates for multiple descriptions


Consider a sequence of independent identically distributed (i.i.d.) random variables X,, X,, . ., X, and a distortion measure d( 4, ,$) on the estimates X, of X,. Two descriptions i(X) E { 1,2; , 2flRl) and j(X) E (1,2,...,2”R2] are given of the sequenceX=(X1,X2;..,Xn). From these two descriptions, three estimates J%?((i(X)), X,(j(X)), and X,( i( X), j(X)) are formed, with resulting expected distortions
