Abstract: A method of post-processing in an audio decoder a signal reconstructed by time and frequency shaping (805, 807) of an excitation signal obtained from an estimated parameter in a first frequency band, said time and frequency shaping being effected at least on the basis of a time envelope and a received and decoded (801, 802) frequency envelope in a second frequency band. The method includes, after said shaping (805, 807), the steps of comparing the amplitude of said reconstructed signal to said received and decoded time envelope and, in the event of exceeding a threshold that is function of said time envelope, applying amplitude compression to said reconstructed signal. Also disclosed is a post-processing module adapted to execute the method, and an audio decoder.

Abstract: The invention relates to the code conversion of digital signals, particularly voice signals, and in particular coding according to a second format from information obtained by carrying out a coding according to a first format. These first and second formats use LPC (linear predictive coding) short-term prediction models on digital signal sample blocks while using filters represented by respective LPC coefficients. The LPC coefficients of the second format are determined from an interpolation on the representative values of the LPC coefficients of at least the first format, between at least one given block and a preceding block. According to the invention, the interpolation (43), is dynamically effected while selecting (42), for each current block, at least one interpolation factor (α) among a preselection of factors according to a predetermined criterion such as a stationarity criterion of the digital signal (41).

Abstract: The invention concerns a mobile telecommunication network comprising a plurality of terminals and an allocating entity adapted to allocate radio resources. One radio resource is associated with a transmission power. One terminal of the network is selected (21) based on at least one transmission power respectively associated with at least one radio resource previously allocated to the selected terminal. Thereafter, an available radio resource is allocated (22) to the selected terminal. Then, a transmission power is associated (23) with the radio resources previously allocated to the selected terminal, so as to reduce the total transmission power allocated to the selected terminal. The previous steps are repeated (24) as long as at least one available radio resource fulfills an allocation condition.
