摘要： The system includes a base station (1) which communicates with a plurality of data carriers (2.sub.1, 2.sub.2) via wireless links. In order to enable the station (1) to identify several data carriers simultaneously, the system includes a device (15) for the separation of sources and also several demodulation units (12.sub.1, 12.sub.2).Depending on the type of modulation, the type of link used, and the arrangement of the source separation device (15) with respect to the demodulation units, the signals received by the source separation device can be convolutional mixtures or instantaneous linear mixtures of the signals transmitted by the data carriers. In order to process the different types of signal received, the source separation device may have a recursive structure, a direct structure or a mixed structure. Adaptation means (105) calculate filtering coefficients which are adapted to enable the source separation device (15) to separate the estimated identification signals for each data carrier requesting communication with the base station.

摘要： Signal transmission system includes a processor (SEPAR) for isolating an estimate (IL) for at least one wanted signal (XL) contained in at least one mixed signal (Ea). At least one sensor (Ma) detects the mixed signal which includes at least the wanted signal (XL) and at least two correlated interference signals (Pa, Pb) generated in response respectively to two correlated electric signals (CRa, CRb).

摘要： A telephone is disclosed having an automatic gain control circuit and a processor which separates a local signal into a sound signal and a speech signal. The automatic gain control circuit selects a gain value based on sound levels of the sound signal when the speech signal indicates an absence of speech. The telephone also has a variable gain amplifier to amplify a received signal. The gain of the amplifier is selected from stored gain values which are stored in a memory of the telephone in a table format and are a function of the sound signal and volume levels of the sound signal chosen by a user. An input device of the telephone allows the user to select one of the volume levels.

摘要： A source separation system (10) processes input signals formed by mixtures of primary signals originating from sources and estimates the primary signals so that the estimates do not differ even in the presence of non-stationary input signals. The system includes a first separation sub-assembly (12) which produces first estimates of the primary signals, a second sub-assembly (14) which adaptively determines the separation coefficients, and a third sub-assembly (15) which standardizes the first estimates and produces first standardized estimates used for the calculation of the separation coefficients. An output module (17) produces estimates which have between them the same proportionality ratio as that existing between the primary signals. A selection module (19) avoids an estimate being duplicated on various outputs in the case where certain primary signals are absent or very weak.

摘要： A source characterization system (8) which, starting from linear convolutive mixtures E(t) of primary signals X(t) from sources (S1-Sn), determines signals F(t) which form an estimate of a characteristic variable of at least one primary signal X(t). This variable may be an average energy, a spectral density or an autocorrelation function. A pre-processing device (20) enables the signals E(t) from the mixtures to be pre-processed before they are applied to the source separation device (10). The measured variable may serve to retroact on the operation of the sources. The source characterization system may be used for the control of apparatuses for transmitting and/or receiving electric, acoustic or electromagnetic signals.
