Abstract: An apparatus and method for multiplexing channel data for supporting variable transmission rate are provided to implement efficiently demodulator and support various transmission rates. The channel data multiplexer(20) comprises a controller(200), an input terminal dual-port block memory(DPBM: Dual Port Block Memory)(201), and an output terminal DPBM(202) and multiplexers(203, 204). The controller controls data read and write of the input terminal and output terminal according to the transmission mode. The controller controls the address processing and clock speed about data output of the first multiplexer. Multi-channel base zone data is input to the input terminal DPBM. The input terminal DPBM stores base zone data of all channels for one time slot. The output terminal DPBM temporarily stores data stored in the input terminal. The multiplexer of the output terminal time-multiplexes data stored in the output terminal and send it to the demodulator(21).

Abstract: A method for measuring the demodulation performance of a communication system and an apparatus thereof are provided to perform the measurement regardless of the location of a terminal station or central station. A communication unit(102) of a measuring equipment(100) transceives commands, data and signals with a terminal station(110) and a central station(120). A controller(104) of the measuring equipment controls the modulation for test pattern data of the terminal station, and then controls the modulated test pattern data to be transmitted to the central station. The controller controls the central station so as to compare the demodulation result with the test pattern data. The communication unit receives the comparison result from the central station.
