2016, Signal ProcessingCitation Excerpt :In particular, it has been shown that compared to the one unrestricted quantizer, the models from [2] and [3] provide high quality of the Laplacian source signals at about 1 bit/sample lower bit rate, which is beneficial from the compression point of view. Unlike [2] and [3], where the quantizer models are composed of SQs with an equal number of quantization levels, the models proposed in [4,5] are composed of SQs with an unequal number of quantization levels. To provide the highest possible quality of the quantized signal, given fixed bit rate, the support region thresholds of SQs observed in [2–5] have been optimized.

2013, Applied Soft Computing JournalCitation Excerpt :Speech coding is to transform the analog signals of speech into digital signals following some certain rules. The basic methods of speech coding are waveform coding [1], parametric coding [2] and hybrid coding [3]. Waveform coding makes effort to keep consistent with the original waveform, which has strong adaptability and high speech quality.
