ASK4

说明：  power allocation in NOMA

OFDM仿真程序，信道估计采用LS,MMSE,LMMSE,DCT等方法，做了个比较，ofdm那个是主程序(OFDM simulation program, channel estimation using LS, MMSE, LMMSE, DCT and so on, made a comparison, ofdm that is the main program)

说明：  Clarke_Jakes_Zheng模型matlab仿真(Clarke_Jakes_Zheng-matlab)

光纤通信系统里的相干系统仿真，相干通信系统中的单载波4QAM信号仿真(coherent fiber communication)

Performace analysis of Zero Forcing detection in (2,2) MIMO system using 4 QAM modulation in Rayleigh Flat Fading Channel

自己做的CRC16校验例子，输入16进制数据，数据之间用空格，得到校验字节(The CRC16 checksum own example, enter the hexadecimal data, with a space between the data check byte)

说明：  FBMC框架的搭建，和OQAM+PPN多项滤波器，大概框架都有(The construction of fbmc framework and OQAM + PPN multiple filters, probably all of them have)

说明：  设计一个巴特沃兹数字低通滤波器，其技术指标为：3dB带宽为0.2π，阻带截止频率为0.3π，通带纹波为1dB，阻带衰减大于30dB，采样间隔T=10ms。 1）采用冲激响应不变法； 2）采用双线性变换法设计； 3）采用FIR的窗函数（Hanning窗、Hamming窗或Blackman窗）设计。(A Butterworth digital low-pass filter is designed. Its technical specifications are: 3 dB bandwidth is 0.2 pi, stopband cut-off frequency is 0.3 pi, passband ripple is 1 dB, stopband attenuation is more than 30 dB, sampling interval T=10 Ms. 1) Impulse response invariance method is adopted. 2) Design by bilinear transformation method; 3) FIR window function (Hanning window, Hamming window or Blackman window) is used to design.)

用VB编写的串口调试助手，附带51程序，大家可以学习，很经典，很地道(With VB serial debugging assistant, with 51 programs)
