3G system design and simulation stage Agilent ADS (AdvancedDesi-gnSystem) is an EDA tool specifically designed for electronic systems and circuit design simulation. It can complete all required design work, including system-level design, DSP design, RFIC design, microwave circuit design, RF circuit board design, etc. . It provides the most complete system and circuit computer and semi-physical simulation functions. Electronic system full-system model simulation, users can quickly build a complete communication system; at the same time use the test module provided by the software, the modulation performance of the transmitter, the demodulation algorithm and performance of the receiver, and the entire system under various conditions Quick evaluation of bit error performance; The most complete wireless communication design library includes GSM, EDGE, CDMA, CDMA2000, 1xEVo, 1xEvDv, WCDMA, TD-SCDMA, WLAN, DTV, etc. The 3G design library contains the algorithm modules involved in all specifications, such as data interleaving, scrambling, framing, spread spectrum, modulation, channel model, demodulation, despreading, descrambling, deinterleaving, etc., prepared according to the corresponding standards and protocols ; Establishment of antenna and channel transmission models (such as antenna propagation, signal fading, multipath effects, etc.); RFIC design simulation, connected to the network analyzer to complete the modeling of the device; Signal modulation / demodulation processing analysis and digital signal processing algorithm implementation; The cascading simulation of the subsystem, and the model of the communication channel are added at the same time, the simulation of the entire communication system link can be carried out; The unique function of ADS is that it can also be dynamically connected with various actual test instruments, closely linking the results of software simulation with the actual testing of test instruments, so as to complete the semi-physical simulation work and expand the application field of traditional EDA software simulation design. 3G network equipment test The Agilent vector network analyzer E5071C has the most excellent index performance and the most comprehensive test function among the same class products in the industry. Now Agilent is constantly developing new vector network analyzers to continuously meet the needs of 3G system component testing. Agilent vector signal generators MXG, ESG and X series signal analyzers provide a general RF test solution that can help R & D engineers and manufacturers quickly bring high-quality, low-cost 3G base stations to the market. 3G terminal test Based on the E5515C hardware platform, the Agilent 8960 series provides two versions of laboratory application software (LA) and test application software (TA) for parameter measurement, base station simulation, and protocol test functions, as well as wireless transceiver calibration and test capabilities. In addition to the basic calibration function, the Agilent 8960 wireless communication tester provides multiple enhanced calibration methods for different mobile phone solutions, such as dynamic power calibration (DPOW), zero-mid frequency calibration and frequency amplitude time calibration (PAvT), etc. These calibration methods greatly reduce the traditional calibration time, increase the production line capacity and reduce manufacturing costs. Through flexible configuration changes, all 3G standard test and measurement solutions including TD-SCDMAHSPA are provided to ensure that you can easily deal with all aspects of R & D, production and maintenance, while protecting your test investment costs for a long time.
