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.
利用聽覺系統的掩蔽特性，提出了一種優化的語音增強方法。
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也引起光脈沖信號偏振度（DOP）的下降，從而嚴重影響光偏振複用系統的性能。
A kind of single input channel speech enhancement algorithm based on signal subspace is studied for enhancement of speech degraded by colored additive noise.
針對加性有色噪聲乾擾，提出了一種單通道輸入基於信號子空間的語音增強算法。
