Abstract: A delay unit is provided to delay adapting modes of a codec if channel communication conditions are improving. A less robust mode having a higher intrinsic quality is selected only after some delay. The quality of the communication is measured to give quality values for successive measurement occasions. The delay unit comprises a plurality of memory cells in a memory for storing the quality values of the communication conditions of the channel for the most recent measurement occasions. A selector operates according to an algorithm for selecting one of the memory cells. The content of the selected cell is used to set the mode of the codec.

Abstract: In a radio communication system in a mobile to mobile call with one good (AMR102) and bad (AMR515) radio link, the good radio (AMR102) link is forced by the poor (AMR515) link to use a more robust AMR coded mode (AMR515) and thereby using excessive power (232). A capacity loss in such system is avoided by adjusting the power level (212) for the connection with the good link (AMR102).

Abstract: The available delay budget for a full-duplex communication is distributed between the links depending on their activity, present and near history. By keeping track on if a link in a full-duplex communication system is active or inactive, i.e. Knowing the information value of the transferred data, coding procedures having larger coding delays than normally accepted can be used for active links, if the opposite link simultaneously is inactive. Since the user sensibility for delays is as largest at the moment a link becomes active, coding procedures having smaller coding delays than normally used are assigned at the moment a link becomes active. The coding delay is subsequently increased. Preferably, the round-trip delay is controlled to be kept smaller than a requested maximum value.

Abstract: A method and arrangement for dynamically adapting thresholds used for selecting a codec mode to be used is presented. Thresholds are adapted in response to the current received signal quality. An estimate of actual prevailing received signal quality is obtained on which the adaptation is based. The present invention can be applied either on the mobile terminal side or on the network side, working on the uplink and/or the downlink. The thresholds can be modified on the receiving side, or, when operating in the network and working on the downlink, the threshold adaptation can be initiated in the terminal.

Abstract: A parametric model is used for error concealment. The model filter allows for recovering signal components of original audio channel signals that now are lost or erroneous from signal components of at least one other audio channel. During error-free reception of valid frames, the parameters of that model will be derived and stored. In case of frame loss or frame error affecting the multi-channel information, a conjecture of the missing information is recovered by applying the model, using the stored parameters. In case of several subsequent lost or erroneous frames, it is possible either to use the parameters derived during the last valid frame or to use parameters derived from the recovered multi-channel information of the respective previous invalid frame. Furthermore, if there are long sequences of lost frames, it can be beneficial to apply some gradual muting of the model parameters, which essentially results in a gradual muting of the model parameters.

Abstract: Signals of different channels (C1-CN) are combined into one mono signal (x). A set of adaptive filters, preferably one for each channel (C1-CN), is derived in a respective filter adaptation unit (30:1-30:N). When an adaptive filter is applied to the mono signal (x) it reconstructs the signal of the respective channel (C1-CN) under a perceptual constraint. The perceptual constraint is a gain and/or shape constraint. The gain constraint allows the preservation of the relative energy between the channels (C1-CN) while the shape constraint allows more stability by avoiding unnecessary filtering of spectral nulls. The transmitted parameters are the mono signal (x), in encoded form, and the parameters (p1-pN) of the adaptive filters, preferably also encoded. The receiver reconstructs the signal of the different channels by applying the adaptive filters and possibly some additional post-processing.
