利用MCMA对bpsk,qpsk,8psk进行盲均衡，并且求取误码率画出星座图(The use of MCMA on BPSK, QPSK,8PSK blind equalization, and calculating BER draw the constellation diagram)

6678的网口程序 已经调试成功了 适用于6678开发板(6678 NDK net project GE ndk me let net project GE ndk me let project GE ndk me let)

说明：  matlab的bpsk，qpsk，msk，qam打包下载，不是自带的程序函数。按照通信框图做的程序(MATLAB，bpsk，qpsk，msk，qam)

用DFT (FFT)对连续信号进行频谱分析(Spectrum Analysis of Continuous Signals Using DFT (FFT))

这是一本国外的经典教材，讲述了现阶段所有数字信号处理的FPGA实现，从第二章讲述二进制的算法到现阶段数字信号处理的研究热点，基于FPGA实现！包括FIR，自适应滤波，纠错码，调制解调，加密，傅立叶变换等等。更难能可贵的是每个例子都有VHDL和Verilog代码！！(This is a classic foreign materials, described at this stage all the digital signal processing FPGA, from the second chapter about the binary digital signal processing algorithms to the current stage of research focus, based on FPGA implementation! Including FIR, adaptive filtering, error-correcting codes, modulation and demodulation, encryption, Fourier transform and so on. Even more valuable is that each case has a VHDL and Verilog code! !)

通过串口解析MODBUS协议 读开关量型的输入信号 读保持寄存器上的内容 批量写数据到保持寄存器(Resolving MODBUS Protocol through Serial Port Input signal of reading switch type Read and hold registers Write data in batches to hold registers)

两种非参数估计方法 核估计 局部线性估计(kernel smoothing local constant regression )

QT环境下开发的，用于测试电力通讯规约IEC103的一个程序(QT development environment for the testing of electrical communications statute a procedure IEC103)

说明：  matlab仿真LDPC码，对采样点数进行PPM编码，此代码加了保护时隙(The LDPC code is simulated by matlab, and the sampling points are encoded by PPM, which adds protection time slot.)

一个完整的ofdm调制系统的仿真程序，包含PN码自动生成，串并转换等各功能模块和算法，重点针对不同信道条件对常用及各种信道盲均衡算法进行仿真分析比较，对不同原型滤波器算法进行研究分析，分析比较QAM系统，供博士毕业论文参考(Ofdm modulation of a complete system simulation program, including automatically generated PN code, and convert the string Other functional modules and algorithms, focusing on a different channel conditions and a variety of common blind channels are Balance simulation algorithm analysis and comparison of different research and analysis prototype filter algorithm, sub- Analysis of more QAM systems, Ph.D. thesis for reference)
