传感信号无线数字传输系统的设计与实现.kdh(err)

xilinx CTC IPcore(encoder 和 decoder)的测试，经过AWGN信道。 -This simulation uses a AWGN module to include noise as part of the simulation. Prior to running the simulation, the UniSim models for the encoder and decoder must be generated as well as the AWGN module.

FPGA 帧同步源代码 调试无错误 ALTERA 平台(Frame synchronization FPGA)

FPGA驱动高输入电压范围的ADS8509芯片，采样范围广，适合前端大信号处理(FPGA drive a high input voltage range ADS8509 chip, sampling a wide range, suitable for large front-end signal processing)

代码文件夹： ARVI_FSM.v为顶层文件，用于模拟时用。 dataHex.dat 为模拟输入文件（只有10行，象征的意思。实际我们模拟时，dataHex.dat文件足有1个多GB） dataFormat.dat为输入文件对应的带格式的文件 使用modelsim模拟时，将dataHex.dat名字改为CPUContext.txt 结果: result.txt (Code folder: ARVI_FSM.v for top-level documents used for the simulation. dataHex.dat for analog input files (only 10 line, the meaning of the symbol. actual simulation we, dataHex.dat documents have more than one full GB) dataFormat.dat for the input file the corresponding file with modelsim simulation used to dataHex.dat name to CPUContext.txt results: result.txt)

ep9351芯片的一个读取寄存器的测试程序，因为他的读取方式跟别的i2c设备不同，所以重新封装了一些i2c读写的接口。(one read ep9351 chip registers testing procedures, because he read i2c device with another different way, so repackaging some i2c interface to read and write.)

基于VHDL的SDH专用芯片的TOP-DOWN设计， 内有全套源码以及图片，内容详尽，绝对真实可靠！(VHDL based on the SDH ASIC Design TOP-DOWN, which has a full set of source code, as well as pictures, and detailed, reliable and absolutely true!)

实现多路可变时分复用，包括复接器，解复接，比特同步，帧同步，分频器(Implement multi-channel variable time division multiplexing, including multiplexer, demultiplexing, bit synchronization, frame synchronization, frequency divider)

小波包分解，重构轴承振动信号，Hilbert包络，FFT进行频谱分析，以获得轴承故障频率。(Wavelet packet decomposition, reconstruction of bearing vibration signal, Hilbert envelope, FFT spectrum analysis to obtain the bearing fault frequencies.)
