摘要： Various embodiments for components and associated methods that can be used in a binaural speech enhancement system are described. The components can be used, for example, as a pre-processor for a hearing instrument and provide binaural output signals based on binaural sets of spatially distinct input signals that include one or more input signals. The binaural signal processing can be performed by at least one of a binaural spatial noise reduction unit and a perceptual binaural speech enhancement unit. The binaural spatial noise reduction unit performs noise reduction while preferably preserving the binaural cues of the sound sources. The perceptual binaural speech enhancement unit is based on auditory scene analysis and uses acoustic cues to segregate speech components from noise components in the input signals and to enhance the speech components in the binaural output signals.

摘要： A method of determining IQ imbalance introduced on an RF multicarrier signal received via a channel on a direct conversion analog receiver is disclosed. In one embodiment, the method comprises i) receiving a training signal on the receiver, ii) demodulating the training signal on the receiver, iii) estimating a first frequency domain channel characteristic of the channel based on the demodulated training signal, iv) defining a predetermined relationship between a corrected frequency domain channel characteristic of the channel and the first channel characteristic, the predetermined relationship comprising at least one IQ imbalance parameter, and v) determining the at least one IQ imbalance parameter such that the corrected channel characteristic satisfies a channel constraint.
