Radix-2 FFT processor using Radix-2 Cordic Algorithm

LDPC码的FPGA实现，大家相互学习下。。(the code of LDPC implementation by FPGA)

基于 quartus 2 的 lte 信道估计verilog hdl代码 只有功能仿真 时序仿真自己加sdc文件并且调整testbench的clk才能做出来(Estimated Verilog HDL code based Quartus lte channel only functional simulation timing simulation plus sdc file and adjust the testbench clk to do it)

在赛灵思的FPGA上实现turbo码的编码程序,使用Verilog语言实现。(Implemented on Xilinx FPGA in the turbo coding principle, the use of Verilog language.)

使用VHDL编写语言，巧妙的利用计数器和循环输出一个坐标系，由于VHDL出现负数比较麻烦，全部由正数代替，输出一个原点在中心，半径128的256×256的坐标。方便坐标变换以及用此坐标做算法。(Use of VHDL language, clever use of counter and loop outputs a coordinate system, because VHDL negative too much trouble, all replaced by a positive number, the output an origin at the center, radius 128 256 256 coordinates. Convenient coordinate transformation and coordinate to do with this algorithm.)

说明：  基于FPGA的Veilog HDL实现代码，简单明了，希望能帮助verilog的初学者……(ＤＤＳ　based on Verilog ＤＨＬ for FPGA　)

Verilog UART is written in this file

ise平台模拟UART，并与PC机实现收发（+1）(ISE platform simulation UART and transceiver.)

fpga的一些经验之谈，对初学者比较有用，都是些容易出错误的地方(FPGA some experiences, more useful for beginners, are more vulnerable to the wrong place)
