14565 随着5G商用网络的快速建设,国内5G网络测试设备存在大量空缺。 With the rapid construction of 5G commercial network，there is a lot of vacancy in domestic 5Gnetwork test equipment．
14566 为此,设计了一种适用于5G终端模拟器的3.5 GHz频段双通道射频前端。 A 3．5 GHz dual－channel radio frequency( ＲF) front－end for 5G terminal simulatoris designed．
14567 该射频前端结合了ADRV9009芯片,可同时支持双通道收发,具有器件数少、设计复杂度低的特点。 This ＲF front－end with ADＲV9009 chip supports dual－channel ＲF transceiver at the sametime，and it is featured by fewer devices and lower design complexity．
14568 实测结果表明,该射频前端性能稳定,接收灵敏度为-85 d Bm,噪声系数小于2.6 dB,256QAM调制下发射信号的误差矢量幅度为1.43%,达到了5G终端模拟器的设计要求。 The experimental results show that theＲF front－end has stable performance，the receiving sensitivity is －85 dBm and noise figure is less than 2．6dB，error vector magnitude of the transmitted signal at 256QAM modulation is 1．43%，which has achievedthe design requirements of 5G terminal simulator
14569 随着软件无线电技术的迅速发展,越来越多厂家开展了基于软件无线电标准的技术研究和产品研制。 With the rapid development of software defined radio( SDＲ) technology，more and more manufacturers have carried out technical research and products development based on SDＲ standard．
14570 由于各厂家对标准的理解不一致,研制软件产品的实现存在差异,导致未经符合性测试的软件之间不能相互兼容,需花费大量时间来进行波形移植开发和系统集成。 However，due to the different understanding of the standards，there are differences in the implementation of differentproducts，as a result，the softwares that have not passed the conformance test are not compatible，so thatplenty of time will be spended on waveform migration and system integration．
14571 针对该问题,提出了一种软件无线电系统标准符合性测试系统的实现方式,给出了系统测试内容、测试方法和实现方式,设计实现了一套软件无线电标准符合性测试系统,并进行了测试验证。 For the problem，a realizationmethod of SDＲ standard compliance test system is proposed，and the test content，test method and implementation technology are described．A whole set of SDＲ standard conformance test system is designed，implemented and tested．
14572 测试结果表明,该测试系统可满足从单一软件产品到整机设备产品的符合性测试需求。 The test results show that the designed test system meets the needs of compliance testfrom single software to equipment product
14573 为了满足人们日益增长的数据流量需求,未来无线通信系统将向更小的小区部署迁移。 In order to meet the increasing demand for data traffic，wireless communication systems will bemigrated to smaller cells in the future．
14574 小蜂窝网络是下一代无线通信系统的关键技术,也是适应未来更加复杂通信环境的有效途径。 Small cell network is a key technology of the next－generation wirelesscommunication systems and an effective way to adapt to the more complex communication environments inthe future．
