| 发明名称 | Device for improving the intelligibility of speech in a multi-user communication system | ||
| 摘要 | A device for improving the intelligibility of a signal arising from a source subjected to a noisy environment, said source marking the signal with a specific signature, the device comprising a processing circuit receiving the signal; and means for analyzing the signal and parameterizing the processing circuit according to characteristics of the signature present in the signal. A first channel with low distortion conveys the signal from the source to the means for analyzing, and a second channel, susceptible to introduce a distortion, conveys the signal from the source to the processing circuit. | ||

| 主权项 | 1. A device for improving the intelligibility of a signal arising from a source subjected to a noisy environment, said source marking the signal with a specific signature, device comprising: a processing circuit receiving the signal; and a signal analyzer parameterizing the processing circuit according to characteristics of the signature present in the signal; a first channel with low distortion conveying the signal from the source to the analyzer; a second channel susceptible to introduce a distortion and conveying the signal from the source to the processing circuit; and a variable gain amplifier located upstream of the second channel, controlled by the analyzer according to the amplitude of the signal in the first channel. | ||
