Figure 1From: Adaptive Long-Term Coding of LSF Parameters Trajectories for Large-Delay/Very- to Ultra-Low Bit-Rate Speech CodingBlock diagram of the LT quantization of LSF parameters. The decoder (bottom part of the diagram) is actually included in the encoder, since the algorithm for estimating the order P and the LT model coefficients is an analysis-by-synthesis process (see Section 3.2).Back to article page
