(English Abstract) |
Recently, in an information-oriented society, the rapidly growing mobile telecommunication field has outstandingly been developed in keeping with world telecommunication market's development, advancement of relative technology and commercial business of digital service in the world of MTS(mobile telecommunication service) such as FPLMTS(future public land mobile telecommunication service) for international roaming and developed multimedia network services.[1%u223C5]
Therefore, in this paper, to apply existing TDMA(time division multiple access), FDMA (frequency division multiple access), CDMA(code division multiple access) methods, hardware system's changelessness, international roaming, multimedia network service and every other irrelative multiple access method to the global triple mode access modem, the baseband designed. The purpose of this paper is to determine distinct using method in a demodulation with abstracting distinguished characteristic property from each multiple access method and allow easier connections of recipient within the wanted areas.
As we develop this triple mode multiple demodulator and discriminator, we will contribute to the technical evolution of mobile telecommunication for the third generation, and stay ahead in the interior technical accumulation in addition to international intercourse as to mobile telecommunication.
