Description: 文章提出了基于多带语减法改进的增强系统，并在TI会司的浮点处理器TMS320C6713上实现。改进的多带语减法将信号频语非线性的分成4个互不重叠的频带， 每个频带分别做不同系数的语减运算， 因此能很好的滤除有色噪声。工程实现证明此设计能有效的抑制色噪声和音乐噪声， 即便在低信嗓比环境也能有较好增强效果.-In this paper, a language based on multi-band subtraction improved augmentation system, and TI will Division TMS320C6713 floating-point processor to achieve. Improved multi-band frequency signal subtraction language phrase is divided into four non-linear non-overlapping frequency bands, each band separately by different coefficient computing language, so they can filter out a good colored noise. Proves that the design works to achieve effective inhibition of color noise and music noise, even in low sNR environment can also enhance the effect of better.
