TD-SCDMA Digital Wireless Communications Test Set Calibration Thchnology Research

TD-SCDMA as a Chinese independent intellectual property rights of the3G standards, it broke the long-term since developed countries in international mobile communication standard monopoly on status. This standard was adopted by ITU in2000become one of the third generation mobile communication international mainstream standard. Meanwhile, in TD-SCDMA standard on the basis of further enhancing the encryption method, expand TD-SCDMA in military field has a wide application prospect.TD-SCDMA Digital Wireless Communications Test Set are used widely In TD-SCDMA related measuring equipment. At present,TD-SCDMA in civil and military application prospect drive lots of manufacturers including StarPoint, ZCTT, Agilent, Japan Anristu, Germany R&S and so on to provide their respective TD-SCDMA digital mobile communication comprehensive test methods and the corresponding equipment. In order to ensure the normal operation of these equipments the calibration is indispensable.This paper mainly completed work is to research TD-SCDMA Digital Wireless Communications Test Set calibration methods, according to the key parameters calibration principle establish TD-SCDMA Digital Wireless Communications Test Set calibration device; Through the actual calibration test, complete uncertainty evaluation and technology assessment of the calibration device; complete TD-SCDMA Digital Wireless Communications Test Set calibration device CNAS calibration ability of accreditation.
