Temporal decomposition based on a rate-distortion criterion

This letter addresses a temporal decomposition (TD) technique that is based on a rate-distortion criterion. In the pro posed TD scheme, a set of the interpolation functions is constructed froth the given training corpus, and the optimum target points are found in the sense of minimizing, pot only spectral distortion, but also bit rates. The results of the simulation show that an average spectral distortion of about 1.4 dB can be achieved at an average bit rate of about 8 bits/frame.
