Datang is THE largest manufacture behind td-scdma, now listen to their introduction to themselves taken from their ads dated 1-5-01.
The employment advertise unit introduces: Mainly is engaged in IS-95 the CDMA mobile communication system and the cdma2000 third generation mobile communication system development. The territory of research involves communications system domain and so on signal processing, correspondence agreement and exchange, network. Is the home most early carries on the unit which IS-95 the CDMA system technology research and the equipment develops, once undertook counts the item of national significant item and yields the significant result, and the success developed the our country first set has the independent intellectual property rights, integrity IS-95 the CDMA system. In April, 2000, this research department (and cooperation unit united) first time publicly demonstrates our country independent development first IS-95 the CDMA complete set system equipment, in under this system composition network environment, carried on between between the many commercial handsets, the handset and the fixed telephone telephone conversation experiment. 基站 and 基站 the controller development has not used the overseas special-purpose CDMA chip, completely used FPGA and the DSP realization plan which own developed, used the FPGA realization baseband wide frequency solution expands, DSP realization channel decoding and sounder. After indicates our country continues GSM, also comprehensively grasped IS-95 the CDMA core technology. And the industry has the vital significance to our country third generation mobile communication system research development. In the system the switchboard and belongs to the position register has realized commercial, 基站 and 基站 the controller also locates inside the product advancement. At present is carrying on the cdma2000-1x third generation mobile communication core technology and 基站 the subsystem research and the development. Estimates in 2001 carries on scene experiments and argues vigorously in 2001 year's end ago enters commercial use. (bablefish doesn't know "base station").
