More Information
Summary: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.
