According to the speech spectrum distribution characteristics in the time - frequency dimension , this paper proposes the posterior bark signal - to - noise ratio to estimate the speech content , designs the subtraction parameter again in the frequency band from 2khz to 4khz . the simulations show that the method in this paper can increase the output
本文依据语音语谱的时-频域分布特性,提出利用后验bark信噪比来估计出敏感频段的语音含量,重新设计2khz ~ 4khz频段减参数,尽量保护敏感频段的语音信息。
At the beginning of this thesis , the principle of fiber fabry - perot strain sensor is presented briefly , and the influence on the results of the peak - to - peak algorithm , brought by the spectrum distribution of light source , wavelength quantification or the noise in the output of the fabry - perot sensor is investigated . the limitation of the peak - to - peak algorithm is pointed out
论文首先阐述了光纤法珀应变传感器的测量原理，分析了实际光源光谱的非均匀分布、波长量化和传感器输出信号中的噪声等对波长域的条纹峰值解调算法的应变测量结果的影响，深入分析了条纹峰值解调算法的局限性。
