摘要

本文对无线应用中的高速数据传输器进行了研究。该工作综述了与调制精度对高速下行分组接入(HSDPA)无线电链路性能影响相关的概念和技术。采用第三代合作伙伴计划(3gpp)[11]中对射频部分定义的无HSDPA(测试模型1)和HSDPA(测试模型5)的测试模型，通过在通过射频发射机(RFTX)链的测试信号中引入一些非线性，对误差矢量幅度(EVM)结果进行了仿真和讨论。从图5 (PSat = 10.1 dBm)、图6 (PSat = 13.2 dBm)和基于3gpp规范的讨论(没有HSDPA的EVM = 17.5%，有HSDPA的EVM = 12.5%)可以得出结论，射频TX路径(PSat =3.1 dBm)必须更线性，以支持HSDPA。通信系统非线性，高速集成电路，无线电发射机，无线局域网。

High speed data transmitters for wireless applications

In this work the high speed data transmitters for wireless applications has been investigated. The work reviews concepts and techniques related to the effect of modulation accuracy on high speed downlink packet access (HSDPA) radio link performance. The Error Vector Magnitude (EVM) results are simulated and discussed by using the test models without HSDPA (test model 1) and with HSDPA (test model 5) defined in 3rd generation partnership project (3gpp) [11 for RF part by introducing some non-linearity in the test signal passing through RF transmitter (RFTX) chain. In this work from the figures 5 (PSat = 10.1 dBm), 6 (PSat = 13.2 dBm) and the discussions based on 3gpp specs (EVM = 17.5 % without HSDPA and 12.5 % with HSDPA) it can be concluded that the RF TX path got to be (PSat =3.1 dBm) more linear to support the HSDPA.
