摘要
本文介绍了一种TD-SCDMA中频数字接收机的设计,该中频接收机利用AD9238实现中频信号采样,利用FPGA实现数字下变频,并采用DSP完成后续信号处理。给出了该接收机硬件电路设计的具体方案,并对各部分硬件电路设计进行了阐述。FPGA的应用使系统灵活性增强,一些信号处理算法可移植到FPGA中实现,提高了系统的运算速度。
A design of TD--SCDMA intermediate frequency digital receiver is introduced in the paper. The AD9238 is used to collect data and FPGA is used to realize digital down conversion and the DSP is used to complete signal processing algorithm.The scheme of system realization is proposed and the design of every hardware circuit is described in detail.The application of FPGA makes the system flexible and some signal processing algorithm can be transplanted to FPGA in order to improve operation speed of the system.
