Joint position and amplitude search of algebraic multipulses
Miguel Arjona Ramírez, M. Gerken · IEEE Transactions on Speech and Audio Processing · 2000
A joint position and amplitude search algorithm is proposed for algebraic multipulse codebooks to be used in code-excited linear predictive (CELP) coders. The joint search complexity is below one quarter that of the focused search and ranks below those of the G.729A and IS-641-A coders. Listening tests indicate an equivalence in perceived quality.
