FFT的VHDL源代码

采用FPGA 来实现一个基于OFDM 技术 的通信系统中的基带数据处理部分，即调制解调器。其中发射部分的调制 器包括：信道编码（Reed-Solomon 编码），交织，星座映射，FFT 和插 入循环前缀等模块。(FPGA to implement a baseband data based on OFDM technology in the communication system processing section, namely modem. Transmitter modulator includes: channel coding (Reed-Solomon coding), interleaving, constellation mapping, FFT and insert the cyclic prefix modules.)

8位并行转穿行发送程序，波特率可自行设置，经检验有实用效果(8-bit parallel transfer walk through the sending program, the baud rate can be set up their own practical effect inspection)

卷积程序的Verilog程序，实现卷积功能(Convolution program Verilog program to achieve convolution function)

this is an peak detection alguritm,in this matlab code u can clean base line noise to have clear ECG signal

使用信号功率计算，检测信号是否到达。从而控制后续模块，以减小系统功耗。(Signal power calculation, the detection signal to reach. To control follow-up modules to reduce system power consumption.)

DDR3 控制器，axi4_full 模式， burst长度为16，应用于xilinx平台。(DDR3 interface controller， axi4_full working mode with burst length 16, can operate on the xilinx platform.)
