The digital part is either a predictive quantizer or a transform code, used to achieve a coding gain.
At the same time, we have deluded ourselves into believing that a small number of "creative" alchemists–software engineers, hedge fund managers, urban developers could transform code, cash and condos into limitless pots of gold.
However, an explicit solution can be found for a variant of this problem obtained by fixing B 1 ′, B 1 ″ and B2, so that the number of bits allocated to each transform code is fixed and it is only required to optimize the bit allocation among the quantizers within each transform code.
CS is a method closely related to transform coding, since a transform code converts input signals, embedded in a high-dimensional space, into signals that lie in a space of significantly smaller dimensions (e.g., wavelet and Fourier transforms) [4].
That is, the terminal with the higher bit rate can independently transform code its input with negligible distortion, and the other terminal can then apply WZ-TC at the minimum rate achievable with "almost unquantized" decoder side-information.
From Table 1, it can be seen that when the sum-rate is greater than its minimum value, the optimal SP-DKLT code approaches a WZ transform code, i.e., no source-splitting occurs.

We applied the method to transform coding and compared the performance of our CVQ with those of Karhunen Loëve transformation (KLT -based coding and non-structured VQ.
This is particularly useful in image compression applications that use transform coding.
Block transform coding is the most popular approach for image and video compression.
The multiprocessor system implements any image transform coding that is represented by a pair of matrix multiplication operations.
Because matched wavelets will have better energy compaction, performance of estimated wavelets is evaluated by computing the transform coding gain.
