Abstract

In a cellular phone terminal, the transmitter, receiver, and combiner consist of common hardware that can be used in multiple communication systems. The channel CODEC, modulator, equalizer, and memory for signal processing programs consist of common hardware that performs signal processing supporting multiple communication systems. The CPU and the memory for the communication control program support different communication control systems, thus providing a multi-mode cellular phone terminal supporting different communication systems with simple design and low cost.

Description

field of invention [0001] The present invention relates to a multi-mode cellular phone terminal supporting multiple communication systems. Background technique [0002] Although cellular phone terminals support various communication systems including PDC (Personal Digital Cellular) system, CDMA (Code Division Multiple It is different in terms of frequency band and bit rate. In order to perform communication / session with these various cellular phone terminals, it is necessary to provide a cellular phone terminal supporting each communication system. [0003] In the related art, in order to support a plurality of communication systems via a single terminal, hardware and software supporting the respective communication systems have been provided, such hardware and software being housed in a single terminal. That is, in the related art, a terminal supporting two communication systems is accommodated in a single cellular phone terminal for a user to select a...
