摘要：To encode the speech quality with reduce the redundancy within samples that resulted from uniform sampling method like PCM, uniform sampling or non-linear sampling coding methods can be considered. However, it is well known that when conventional sampling methods are applied directly to speech signal, the required amount of data is comparable to or more than that of uniform sampling method in noisy. To overcome this problem, a new non-uniform sampling methods is proposed, in which non-uniform sampling is applied to the low-pass filtered speech signal and the remain signals are compensated by the rectified signals with various harmonics.
