Abstract
An all-digital technique for mutual conversion between 32 kbps CVSD encoded signals and 64 kbps standard PCM encoded signals has been proposed. Compared with the existing code conversion schemes, our proposed technique overall eliminates cumulative distortion regardless of the number of the tandem transcodings in the steady state mode (i.e., in the absence of transmission errors). Thus, the algorithm can enhance the performance of the telephone networks.<>
