摘要： PROBLEM TO BE SOLVED: To provide a CDMA mobile station and a CDMA transmission method for this mobile station which realizes a very great flexibility of a system.
SOLUTION: A transmitter 1 comprises a frame structure forming means 11 and a data spreading means 12 using a code sequence, whose spreading factor depends on an original payload data rate. A transmitter 1 further comprises a burst generating means 10 and 11, whose burst has a compressed data obtained by compressing a data block. A duration which is not used for a transmission of the compressed data block is formed in the frame of the frame structure by these means 10 and 11.

摘要： PROBLEM TO BE SOLVED: To make a voice coding device to be connected easily with external appliances. SOLUTION: In a voice coding device 1, four pieces of input connectors 10A, 10B', 10C' and 10D to which audio data in which two channels are multiplexed are possible to be inputted respectively are provided with respect to 6 pieces of encoders 11A to 11F performing respectively the coding of the audio data of one channel. The connection among the connectors 10A to 10D and the encoders 11A to 11F is made to be freely settable, for example, the L and R channels of a main voice and the C channel of the main voice are inputted respectively to the connector 10A and the connector 10B' and the L' and R' channels of a sub-voice and the C' channel of the sub-voice are inputted respectively to the connector 10D and the connector 10C'. Outputs of the encoders 11A to 11C and outputs of the encoders 11D to 11F are multiplexed respectively in multiplexing parts 12A, 12B to be outputted respectively as coded streams of the main voice and the sub-voice. As a result, audio data of two voice modes (3/0) can be inputted to the voice coding device without using an external mixer or the like.

摘要： PURPOSE:To improve the transmission efficiency of a line by recognizing the classification of media of a terminal requesting the setting of a speech path at the time of setting the speech path and selecting a compressing method according to the media. CONSTITUTION:The originating call message from a terminal (PBX) 3a is extracted from the D channel in the slot of a PBX-TDM interface format 24 in the ISDN interface circuit 22a of a multimedia multiplexing device (TDM) 1a. The TDM 1a takes out data (64 kbps) stored within a using slot from the using slot and the classification of media and performs a compression processing by using a data compression/extension circuit 12a composed of plural systems such as a 32 KADPCM and a 16 KLDCELP, etc., according to the classification of media such as sound, 3.1K audio and nonrestrictive digital data, etc. A high speed digial exclusive line multiplexing interface circuit 23a finds out an unused slot or the slot during speech and sets data at proper speed.
