ABSTRACT:
A radio communication apparatus for transmitting a voice signal and a data signal in a multiplex form. The transmitting side of the radio communication apparatus includes: a sampling unit for sampling the voice signal and the data signal and generating a digital voice signal and a digital data signal; a time division unit for dividing the digital voice signal and the digital data signal on the basis of a predetermined period; a modulation unit for modulating the divided digital data signal by a predetermined digital modulation scheme; a unit for compressing the divided digital voice signal at a predetermined compression factor and generating a compressed voice signal; a unit for combining the divided and compressed voice signal and the divided and digitally modulated digital data signal and generating a multiplex signal; and a unit for modulating a carrier signal by the multiplex signal and transmitting the modulated carrier signal as a transmission signal.
