摘要： A method for improving the intelligibility of an incoming telephone signal, including boosting loudness of at least one band of poorly heard frequencies of the signal within at least one band of intensities of the signal, the band lying below a predetermined intensity level at which telephone standard conformance testing is performed, thereby to generate a differentially boosted telephone signal. Alternatively or in addition, intelligibility of sibilants in a narrow band telephone signal is enhanced, by doubling the sampling rate of the narrow band signal by interpolation, thereby to provide a narrow band interpolated signal, generating a harmonic extrapolation signal by harmonically extrapolating from the narrow band interpolated signal thereby to estimate the missing portions of the telephone signal, the harmonic extrapolation comprising a sequence of pulses located at peaks of the interpolated signal, generating a missing energy estimator measure estimating energy missing at high frequency bands of the telephone signal, continuously modulating the amplitude of the pulses in said sequence of pulses based on said missing energy estimator measure, thereby to generate a modulated signal, passing the modulated signal through a shaping filter thereby to obtain a shaped signal, and summing the shaped signal with the interpolated signal.

摘要： An FFT section (102) converts a windowed input noise signal to a frequency spectrum. A spectrum model storage section (103) holds model information concerning a spectrum model. A spectrum model sequence calculating section (104) calculates a spectrum model number sequence corresponding to the amplitude spectrum sequence of the input noise signal by using model information stored in the spectrum model storage section (103). A continuation length model/transition probability calculating section (105) outputs a model parameter by using a spectrum model number sequence calculated by the spectrum model sequence calculating section (104). Thus, a background noise signal with high auditory quality is synthesized.

摘要： An Empirical Mode Decomposition (EMD)-based noise estimation process is disclosed herein that allows for blind estimations of noise power for a given signal under test. The EMD-based noise estimation process is non-parametric and adaptive to a signal, which allows the EMD-based noise estimation process to operate without necessarily having a priori knowledge about the received signal. Existing approaches to spectrum sensing such as Energy Detector (ED) and Maximum Eigenvalue Detector (MED), for example, may be modified to utilize a EMD-based noise estimation process consistent with the present disclosure to shift the same from semi-blind category to fully-blind category.
摘要翻译：本文公开了基于经验模式分解（EMD）的噪声估计过程，其允许针对给定被测信号的噪声功率的盲估计。基于EMD的噪声估计过程是非参数的并且对信号是自适应的，这使得基于EMD的噪声估计过程不需要具有关于接收到的信号的先验知识即可操作。例如，现有的频谱感测方法（例如能量检测器（ED）和最大特征值检测器（MED））可以被修改以利用与本公开一致的基于EMD的噪声估计过程将其从半盲类别转移到完全盲目的类别。
