特殊随机矩阵的生成，包含两个程序，一个可以随机生成行和和列和均为K的0-1矩阵，另一个可以随机生成稀疏矩阵。(Matrix generation,concluding two program,one can generate the 0-1 matrix that have the same row sum and column sum,the other can generate sparce matrix.)

matlab建模与仿真源代码，是一本比较好的仿真教材。(matlab modeling and simulation of the source code, a better simulation textbooks.)

在matlab下，使用hough 算法检测圆形( matlab hough cicle)

通过 MIMOsimSpectralHelp() 输入不同参数，可以模拟和比较在不同结构和环境下MIMO系统的性能；有助于我们理解MIMO。(Enter through MIMOsimSpectralHelp () with different parameters, you can simulate and compare the performance of different structures and environments in MIMO systems help us understand MIMO.)

M-file for simulating a QPSK transmitter by modulating with a pseudo random bit stream. A serial to parallel conversion of the pseudo random bit stream is performed with mapping of two bits per symbol. A cosine and sine carrier is configured and the I and Q symbols modulate these carriers. The I and Q carriers are combined and time and frequency domain plots are provided showing key waveforms at various positions in the QPSK transmitter.
