Encryption of an image is done.The Encryption is based on Stream cipher.

改进LMS法 变步长与泄漏的LMS算法、改进极性LMS法(Improved LMS method LMS algorithm for variable step size and leakage, improved polarity LMS method)

这是本论文的仿真部分，是对MIMO系统理论的验证。本论文将分别从两种情况来对系统进行仿真：不同的信噪比下，发射天线数 为4，接收天线 逐渐增大；不同的信噪比下，接收天线 为4，发射天线数 逐渐增大。然后分别绘出他们的仿真图，并对它进行分析(This is the simulation part of this paper is to verify the theory of MIMO systems. In this paper, two cases will come from the system simulation: different signal to noise ratio, the number of transmission antennas is 4, the receiving antenna is gradually increasing different signal to noise ratio, the receiving antenna 4, gradually increasing the number of transmission antennas Great. And then mapped to their respective simulation map, and analyze it)

Recusive Drawing for a star, it depends on the angle between the edged of the star, also the user sets to witch level he wants the star to be recusivly drawn.
