Abstract: To estimate the response of a system to an input signal, on the one hand the input signal and on the other hand an observation signal, a component of which is said response to the input signal, are received, an error signal is determined by subtracting from the observation signal the input signal filtered by an identification filter representative of the response of said system, and the coefficients of the identification filter are adapted by taking into account the input signal and the error signal. If the adaptation takes into account an adaption stepsize .mu..sub.t, the latter is varied according to: .mu..sub.t =a/(c+d. P2.sub.t /P1.sub.t), where a, c and d denote positive constants, P1.sub.t denotes an estimate of the power of the input signal and P2.sub.t denotes an estimate of the power of the observation signal or of a disturbance component of said observation signal. The variable .mu..sub.t can also be employed to adapt the gains of an echo canceller with adaptive gains.

Abstract: In a device for rejecting the image signal of a signal converted to a predetermined intermediate frequency, a local oscillator supplies a local signal at a frequency chosen according to the frequency of the signal and the intermediate frequency. A first phase-shifter has two passive phase-shifter cells including resistive and capacitive components and respectively connected to the output of the oscillator to supply two mixer signals in phase quadrature. Two mixers receive an input signal containing a signal and its image signal and a respective mixer signal and supply two intermediate signals at the intermediate frequency. A second phase-shifter comprises two passive phase-shifter cells comprising resistive and capacitive components and respectively connected to the outputs of the two mixers to introduce a further phase quadrature relationship between the two intermediate signals. A summing device connected to the outputs of the two passive phase-shifter cells of the second phase-shifter eliminates the image signal.

Abstract: The terminal and the user module are authenticated in a combined manner on the basis of an authentication key calculated on the one hand by the terminal and on the other hand by the network. A session key is firstly calculated by the user module on the basis of a secret user key, of a terminal identification parameter and of a first random number. Calculation of the authentication key by the terminal involves this session key calculated by the user module, a secret terminal identification key and a second random number. The network calculates in the same way the session key and the authentication key by retrieving the secret keys on the basis of the identification parameters transmitted by the terminal. The terminals can then be authenticated by the network independently of the associated user modules.
