PURPOSE: A mobile communication system capable of performing an online function test is provided to insert a test pattern into a BUDA module of a base station system, and to perform the same process as a baseband signal, then to measure a BER(Bit Error Rate) from the test pattern by recovering the test pattern, thereby verifying a function of the BUDA module. CONSTITUTION: A test pattern generator(130) generates a predetermined test pattern. An adder(140) inserts a test pattern into a BUDA module for outputting a baseband signal by processing the baseband signal into an RF signal. A test pattern recoverer(100) recovers the test pattern from a high frequency output signal of the BUDA module. An operator(110) measures a BER by the recovered test pattern. A controller(120) processes the test pattern such that a manager can know assigned and measured results on test pattern information. |
