摘要： A base station unit of a communication device generates control information identical with those generated by other communication devices. The control information includes information defining regions in a radio frame that are used by the communication device and the other communication devices to transmit data. A terminal unit receives data in accordance with the control information. A switching unit changes the connection among the base station unit, the terminal unit and an antenna. When the control information is output from the base station unit, a switch controller operates the switching unit so that the base station unit may be connected to the terminal unit to output the control information to the terminal unit.

摘要： Several encoders perform a local decoding of a speech signal and extract excitation information and vocal tract information from a speech signal for an encoding operation. The transmission rate ratio between the excitation information and the vocal tract information are different for each encoder. An evaluation/selection unit evaluates the quality of decoded signals subjected to a local decoding in each of the encoders, determines the most suitable encoders from among the several encoders based on the result of the evaluation, and selects the most suitable encoder, thereby outputting the selection result as selection information. The decoder decodes a speech signal based on selection information, vocal tract information and excitation information. The evaluation/selection unit selects the output from the encoder in which the quality of a locally decoded signal is the most preferable. When vocal tract information changes little, the vocal tract information is not output, thereby allowing for increased quality of information. As much of the surplus of unused vocal tract information as possible is assigned to a residual signal. Thus, the quality of a decoded speech signal is improved.

摘要： A variable rate coder for transforming an input signal into a low bit rate digital signal, comprising: a plurality of coding units each comprising an output quantizer having a different number of output bits, and each independently transforming the input signal into a respective compressed digital signal. A plurality of bit rate determined circuits are provided to determine an output of one of the plurality of coding units as a candidate output of the coder by a respective individual determining method, in which method, the quality of the signal which is regenerated from the output of each coding unit is compared with an individual predetermined quality evaluating standard, and then the candidate output of the coding unit having the smallest number of output bits, among the candidate outputs of coding units satisfying each standard, is determined as the actual output of the coder. One candidate output, among the plurality of the determined candidate outputs and, which is further determined by a most suitable determining method relative to the level of the input signal, thus is selected as the actual output of the coder. Further, when the number of the output bits in each of the coding units can be variably set, the most suitable number of output bits for the actual output of the coder is calculated based on prediction gains of the coding units, a required signal-to-noise ratio of the coder, and an ADC signal-to-noise ratio at the analog to digital converter, and the number of the output bits in each of the coding units is set based on the above calculated value, before the above operation by the bit rate determining circuits.
