摘要： It is possible to cope with a change of the transmitting capacity in wireless communication such as wireless telephone system. A plurality of transmission channels are set within the transmission frequency band prepared for each base station. When a communication is made between the terminal equipment and the base station through the transmission channels, at least a first transmission channel and a second transmission channel are set as the transmission channel depending on a class of information to be transmitted. The first transmission channel is set to have a fixed transmitting capacity and the second transmission channel is set so that the minimum transmitting capacity may be defined and the transmitting capacity greater than the minimum transmitting capacity may be set depending on the setting condition of the transmission channels within the transmission frequency band prepared.

摘要： A narrow band code book in which parameters of a the region of a narrow band audio signal obtained from patterns of a plurality of audio signals have previously been stored and a wide band code book in which parameters of a time region of a wide band audio signal obtained from the patterns of a plurality of audio signals have previously been stored in correspondence to the code book of the narrow band are prepared. The input narrow band audio signal is analyzed by the code book of the narrow band and is synthesized by the code book of the wide band. In this instance, an autocorrelation is used as parameters of the code books. A signal obtained by up-sampling an LPC residual is used as an exciting source at the time of audio synthesis.

摘要： A narrow band code book in which parameters of a the region of a narrow band audio signal obtained from patterns of a plurality of audio signals have previously been stored and a wide band code book in which parameters of a time region of a wide band audio signal obtained from the patterns of a plurality of audio signals have previously been stored in correspondence to the code book of the narrow band are prepared. The input narrow band audio signal is analyzed by the code book of the narrow band and is synthesized by the code book of the wide band. In this instance, an autocorrelation is used as parameters of the code books. A signal obtained by up-sampling an LPC residual is used as an exciting source at the time of audio synthesis.
