Binary code excited linear prediction (BCELP): new approach to celp coding of speech without codebooks
Redwan A. Salami · Electronics Letters · 1989
A new analysis-by-synthesis speech coding approach able to produce good quality speech in the vicinity of 4.8 kbit/s is presented. The new approach produces the same speech quality as obtained by CELP codecs without needing any excitation codebook storage. The new coder employs a very simple excitation search procedure and possesses an inherent robustness against channel errors. The approach is based on the ternary code excitation CELP introduced in Reference 3.
