Abstract: The quality of comfort noise generated by a speech decoder during non-speech periods is improved by modifying comfort noise parameter values normally used to generate the comfort noise. The comfort noise parameter values are modified in response to variability information associated with a background noise parameter. The modified comfort noise parameter values are then used to generate the comfort noise.

Abstract: An user information channel is established in a call originating exchange, by establishing a sub-channel by giving a sequence number which is unique within each interconnecting link, to input of a selected multiplexer (65). A mapping function is used to obtain a relation between the sequence number and user information channel. The established channel is used for transmitting information to obtain an interconnecting link. A message comprising information about the relation obtained using the mapping function, is transmitted to another exchange, so as to create similar relation at that exchange.

Abstract: Systems and methods for processing a received radio signal in a communication system are described. Initial time synchronization is acquired using a trace operator. Then, a number of channel taps for use in further processing is determined based on the initial time sync, also using a trace operator. A final synchronization position is then selected using the number of channel taps and, if multiple branches are employed to receive the signal, using a determinant-based technique. Finally, a channel estimate is determined using the final synchronization position.

Abstract: The invention relates to a method, device and communication protocol for facilitating communication between private telecommunication network exchanges (10), which are interconnected by an intervening network (20). The method, device and protocol allow the signalling at a Q-reference point in a private telecommunication network exchange device to be unchanged by means of using a mapping function to obtain an interconnecting link between the Q-points in at least two such devices thereby establishing user information channels.

Abstract: Perceptually relevant non-speech information can be preserved during encodin g of an audio signal by determining whether the audio signal includes such information (122, 124, 125). If so, a speech/noise classification of the aud io signal is overriden (43) to prevent misclassification of the audio signal as noise.

Abstract: In producing an approximation of an original speech signal from encoded information about the original speech signal, current parameters (EnPar(i)) associated with a current segment of the original speech signal are determined from the encoded information. Reproduction of a noise component of the original speech signal is improved by using at least one of the current parameters and corresponding previous parameters respectively associated with previous segments of the original speech signal (31, 37, 39) to produce a modified parameter (EnPar(i) mod ). The modified parameter is then used (25, 40) to produce an approximation of the current segment of the original speech signal.
