degraded signal

基本解释

An optimal approach for enhancing a speech signal degraded by uncorrelated stationary additive noise, which exploits auditory perception properties, is proposed.
利用听觉系统的掩蔽特性，提出了一种优化的语音增强方法。
Due to the PMD, the degree of polarization (DOP) of optical signal will also be degraded. This directly impairs the performance of the optical polarization multiplexing (PM) system.
PMD也引起光脉冲信号偏振度（DOP）的下降，从而严重影响光偏振复用系统的性能。
A kind of single input channel speech enhancement algorithm based on signal subspace is studied for enhancement of speech degraded by colored additive noise.
针对加性有色噪声干扰，提出了一种单通道输入基于信号子空间的语音增强算法。
