说明：  空域零陷，首先用doa技术估计直达波方向，然后置零，用于直达波消除。(In spatial nulling, DOA technique is used to estimate the direction of direct wave, and then zeroing is used to eliminate direct wave.)

迭代最近点点云配准算法的matlab实现，最经典的算法(Iterative Closest little cloud registration algorithm matlab realize, the most classical algorithm)

对2*2瑞利衰落BQSK调制的MIMO信道进行均衡，对比ZF、MMSE、ML方法的均衡效果。(Script for computing the BER for BPSK modulation in a Rayleigh fading channel with 2 Tx, 2Rx MIMO channel with MMSE、ZF、ML equalization.)

协作通信中的基础仿真，含有pdf格式文章(cooperative communication Introduction and Simulation)

alculates the PMI to be used, RI feedback right now not included! by Stefan Schwarz

ADRC的仿真示例，自己加入输入再调整参数就可进行仿真了，系统是二阶系统的(ADRC simulation example, the input and then adjust the parameters can be simulated, the system is the two order system.)

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.)

说明：  程序中比较了NOMA和OFDMA在容量方面，附带一篇论文，讲的比较详细(The program compares noma and OFDMA in terms of capacity, with a paper, more detailed)
