- An algorithm reducing search complexity for adaptive codebook is suggested, the solving method, which changes a parameter into LSP parameter, is discussed.
- One is the robustness against channel noise;the other is the computational complexity of codebook search.
- The exact value of gain is calculated and quantized.Fixed quantization is used in adaptive codebook and adaptive quantization is used in fixed codebook.
- A clustering optimization strategy of codebook searching is putforward in this paper based on the realization of G.723.1 coder algorithm.
- The author is going to adapt his play for television.
