数据传输系统的FPGA一体化设计与实现

当前的差分相移键控（DPSK）数据传输系统大多是采用独立的数据调制解调终端设备和收发信设备组成的,集成度低、可靠性较差,存在内部信号量化噪声。通过应用现场可编程门阵列（FPGA）加高速数字信号处理设计技术,将数据传输系统中的信号进行DPSK调制,基带到射频信号的数字上变频,以及信号的解调与射频到基带信号数字下变频进行一体化设计,解决了DPSK调制解调终端设备与射频信道设备相互独立所带来的集成度低、可靠性差,以及设备间信号变换引起信号受损等问题。

Integrated Design and Implementation of Data Transmission System based on FPGA

The current DPSK data transmission system is mostly composed of dedicated digital modem and transceiver,thus resulting in low integration,low reliability and interior quantization noise.By FPGA and high-speed digital signal processing and through the integrated design of signal modulation by DPSK,baseband signal to RF signal by digital up converter,and signal demodulation and RF signal to baseband signal by digital down converter,the problems caused by independence between DPSK modem and RF channel device,s...
