摘　　要：介绍了一种以测试QPSK系统为基础的硬件设计检验方法,结合预失真技术对该测试系统的硬件总体规划及FPGA设计与实现进行了详细的论述,阐明了各个部分的工作原理。最后提出了实现解调同步的简易方法及误码率测试的具体实现。This passage presents a new method of hardware design examination based on a QPSK test system, the total hardware design and the FPGA implementation of which are discussed in detail accompanied with the technique of pre-distortion. Working principle of every part in this system is also clarified during this article. In the end, a simple way to achieve the synchronization between the transmitter and receiver and the specific realization of testing code error are proposed particularly.
