Terminal of a code division multiple access cellular communication system, and a transmit and receive data processing method thereof

摘要

A terminal and a method therefor in which only one digital signal processor DSP is utilized, thereby decoding receive data and encoding transmit data in a code division multiple access cellular communication system. The terminal according to the present invention comprises: a DSP for executing a program which includes a sub-routine for determining receive data bit rate, and encoding data to be transmitted according to a transmit data rate; a controller for controlling encoding and decoding operations of the DSP; a modulator for modulating data encoded by the DSP; a demodulator for demodulating receive data, thereby to input the demodulated data to the DSP; a speech encoder for encoding speech information to be transmitted, thereby to input the encoded speech information to the controller; and a speech decoder for restoring data decoded by the DSP.
