Abstract: PROBLEM TO BE SOLVED: To facilitate communication channel allocation management in a base station without adding equipments by monitoring the overflow condition of a buffer and an error rate and controlling an encoding rate, a channel number and a transmission rate by a controller. SOLUTION: Data from sources 16-20 are received in elastic buffers 22-26 and encoded and interleaved in encoding/interleaving circuits 36-40. Then, the controller 34 monitors the overflow condition of variable rate Walsh encoders 28-32 and controls the encoding rate and the channel number for the buffer. Then, they are modulated in modulation/diffusion devices 42-46 and outputted through a coupler 48 and an RF circuit 50. A receiver 14 inputs them through an antenna 70, demodulation/de-diffusion devices 74-78 and decoding/de- interleaving devices 85-90 to the buffers 92-96. In this case, the controller 34 monitors the error rate and controls the transmission rate. Thus, the allocation management of a communication channel in the base station is facilitated.
