华为FPGA设计全套资料，学习FPGA的朋友可以下载看看。(Huawei FPGA design a full set of materials, friends learning FPGA can download and see.)

说明：  displayport 参考设计，可以对比自己工程做验证，另有参考设计XAPP1178未找到，采用方案为DP159 + Artix7 FPGA(xilinx displayport sink design)

说明：  verilog实现的fft算法，其中还有ifft算法(FFT algorithm based on Verilog)

本程序调试了TI的高精度模数转换芯片ADS1115,此模数转换器采用双积分型，16位，为IIC通信方式，调试较复杂，在对直流采集方面有着广泛的应用(This program debugging TI s high-precision analog-digital conversion chip ADS1115)

pll(phase locked loop) is used to fix the circuit to particular frequency

根据软件无线电的思想，提出了一种新颖的数字信号处理算法，对QPSK信号的相位进行数字化处理，从而实现对QPSK信号的解调.该算法允许收发两端载波存在频差，用数字锁相实现收发端载波的同步，在频偏较大的情况下，估算频偏的大小，自适应设置环路的带宽，实现较短的捕获时间和较好的信噪性能。整个设计基于XILINX公司的ISE开发平台，并用Virtex-II系列FPGA实现。用FPGA实现调制解调器具有体积小、功耗低、集成度高、可软件升级、扰干扰能力强的特点，符合未来通信技术发展的方向。(According to the idea of software radio, a novel digital signal processing algorithm, the phase of QPSK digital signal processing, enabling the demodulation of QPSK signals. This algorithm allows the sending and receiving ends of the carrier frequency difference exists, using digital phase-locked to achieve synchronization of sending and receiving end of the carrier, in the case of large frequency offset, frequency offset estimation of the size, adaptive set the loop bandwidth to achieve shorter acquisition time and better noise performance. The whole design is based on the company XILINX ISE development platform, and Virtex-II series with the FPGA. FPGA realization of a modem with a small size, low power consumption, high integration, software upgrades available, the characteristics of strong interference interference, in line with the future direction of ICT development.)
