A memory-efficient trellis coded quantizer divides consecutive trellis columns into groups or windows each containing the maximum number of columns for which each pair of columns in a window still retains statistical dependence with respect to the states of the column and in relation to any trellis path connecting the two columns. Back searching for code words operates on each individual window, rather than on the overall trellis. Windows are sequentially processed in pairs to derive the code words for the input that has been trellis coded. Required storage is reduced, since trellis and code word storage is required only for the windows currently being processed.
