Abstract
A joint position and amplitude search algorithm is proposed for algebraic m ultipulse codebooks to be used in code-excited linear predictive (CELP) cod ers. The joint search complexity is below one quarter that of the focused s earch and ranks below those of the G.729A and IS-641-A coders. Listening te sts indicate an equivalence in perceived quality.
