Abstract

A data communication apparatus using a radio frequency and a data processing method thereof are provided. A first communication apparatus frequency shift keying and phase shift keying modulates and transmits data from a service server to a radio frequency band. A second communication apparatus modulates, demodulates, and outputs the data. The data communication apparatus using a radio frequency, includes: a data modulation module frequency shift keying and phase shift keying modulates data to a radio frequency band to generate a modulated data signal; and a data transmission module transmitting the modulated data to another communication apparatus.

Description

technical field [0001] The present invention relates to data communication devices and methods using radio frequency (RF). Background technique [0002] A Date Radio Channel (DARC) means a broadcast service that adds digital characteristic signals such as news, stock, and weather information to the remaining frequency band (76kHz frequency band) of the FM band and transmits it. Here, the DARC uses a level controlled minimum shift keying (Level Controlled Minimum Shift Keying, LMSK) modulation scheme to transmit the digital signature signal to the FM band. However, the LMSK transmission scheme has a transmission rate of 16000 bps in specification and is susceptible to noise and errors. [0003] The information disclosed in this Background section is only for enhancement of understanding of the general background of the invention and therefore it may contain information that does not form the prior art that is already known in this country to a person of ordinary skill in the...
