摘要

本文利用一阶和二阶近似样条函数进行了扩展量化器的设计。采用一阶和二阶样条函数逼近最优压缩函数。为了降低所设计模型的实现复杂度，本文提出用不同的样条函数来逼近不同段的最优压缩机函数，即将一阶和二阶样条函数相结合来逼近最优压缩机函数。对所提出的分段数2L = 4 i 2L = 8的压缩量化器所得到的结果进行了综合分析。

Approximation of the optimal compressor function combining different spline functions in segments

In this paper the companding quantizer design using the approximative spline functions of the first and the second degree is done. The spline function of the first degree and the second degree is used for the approximation of the optimal compressor function. In order to reduce realization complexity of the designed model, in this paper it is proposed that the optimal compressor function in different segments is approximated by different spline functions, which means that the approximation of the optimal compressor function is done by combining the spline function of the first degree and the second degree. Comprehensive analysis of the results obtained for the proposed companding quantizer for the number of segments 2L = 4 i 2L = 8 is done.
