New methods for trellis source coding at rates above and below one
Tomas Eriksson, John B. Anderson, M. Novak, Norbert Goertz · 2004
This paper presents new methods trellis source coding at rates above and below one. The new schemes have in common a code design based on branch correlation, a large reproducer alphabet, and an encoder based on either the Viterbi algorithm or a tailbiting MAP technique. The methods are easily adapted to various bit rates, but here only the results for R = 2 and R = 1/2 bits per source sample are presented. Results, demonstrated for the memoryless Gaussian source, show similar or better performances than previous methods with similar coding complexity.
