Abstract: PURPOSE: An apparatus for improving channel quality of analog radio is provided to reduce an error in channel transmission by minimizing a transmission bit number through a voice encoding operation in a transmission mode. CONSTITUTION: In a transmission mode, a transmission signal processor(250A) converts an analog voice signal of a transmission party into a digital signal through a voice input unit(220). The transmission signal processor modulates the digital signal into an analog signal after voice encoding and channel encoding. In a reception mode, a reception signal processor(250B) demodulates the analog voice signal of a reception party into the digital signal. After channel decoding and voice decoding, the reception signal processing unit converts the digital signal into the analog signal.

Abstract: PURPOSE: A method for reducing delay of a voice transmission in a digital voice communication system is provided to abandon data whose packet data rate in a wireless terminal is less than a predetermined rate, when voice delay occurs, thereby reducing the voice delay. CONSTITUTION: A wireless terminal measures a recovery time whenever a voice block is generated(10). The wireless terminal compares the recovery time with a reference value(12). If the recovery time exceeds the reference value, the wireless terminal stores packet data only whose data rate is more than a predetermined rate among packet data generated from a vocoder, and generates the voice block(16). If the recovery time is less than the reference value, the wireless terminal stores all the packet data, and generates the voice block(14). The wireless terminal transmits the generated voice block to a TCP layer(18).
