Evaluation System Architecture for Digital Baseband System of CDMA Mobile Station

摘要

The present invention relates to an evaluation system architecture for a digital baseband system of a CDMA mobile station.;To enhance the competitiveness of the CDMA system, especially the vocoder responsible for encoding and decoding voice signals in the digital baseband of a mobile station, a modem for performing codes, modulation, demodulation and decoding functions, and call processing software based on IS-95 are performed. The first chip of the microcontroller, which is in charge of controlling the entire system, comes first.;However, it is necessary to check whether the digital baseband system of the mobile station performs the call processing algorithm according to the standard in connection with the base station, and at the same time, to check the function at the system level after the 1 chip of each separately manufactured ASICs. Evaluation system is required.;Evaluation system according to the present invention is a basic and essential system to be carried out with the 1chip of CDMA mobile base station digital baseband system, the function check of vocoder including loop-back test, and the call processing program of modem ASIC by message logging. It can also be used for the development of call processing programs themselves.;The evaluation system according to the present invention is the only system having a structure that can check only the digital baseband providing the CDMA source technology in association with the call processing algorithm without including the analog baseband, the IF unit and the RF unit. Its simplicity and simplicity of use due to not including the analog part is characterized by.
