ABSTRACT:
A code-excited linear prediction (CELP) coding method and code divide the residual signal into frequency bands. Codebooks provided for each band decrease in size with increasing band frequency. Reduction in codebook size with increasing frequency together with reduction in sampling rate with decreasing frequency provide reductions in codebook search complexity that allow real time implementation on digital signal processor chips.
