Dynamic adjustment of noise separation in data handling, particularly voice activation
InactiveUS7146314B2Improves voice signal detection abilityData detection is convenientSpeech recognitionDynamic noiseConsecutive frame
Data handling dynamically responds to changing noise power conditions to separate valid data from noise. A reference power level acts as a threshold between dynamically assumed noise and valid data, and dynamically refers to the reference power level changing adaptively with the background noise. The introduction of dynamic noise control in VOX (Voice Activated Transmission) improves a VOX device operation in a noisy environment, even when the background noise profiles are changing. Processing is on a frame by frame basis for successive frames. The threshold is adaptively changed when a comparison of frame signal power to the threshold indicates speech or the absence of speech in the compared frame repeatedly and continuously for a period of time involving plural successive frames having no valid speech or noise above the threshold to correspondingly reduce or increase the threshold by changing the threshold to a value that is a function of the input signal power.

A Maximum Likelihood Sequence Estimator comprises a signal receiver (401) which receives a first signal for decoding. An ISI processor (403) generates a compensation signal from the first signal. The compensation signal represents intersymbol interference outside a channel model window of a Maximum Likelihood Sequence Estimation (MLSE) but does not represent intersymbol interference within the channel model window of the MLSE. A compensation processor (405) generates a compensated signal by compensating the first signal by the compensation signal, e.g. by subtracting the compensation signal from the first signal. The compensated signal is fed to a MLSE decoder (407) which decodes data of the first signal by performing the MLSE on the compensated signal.
