说明：  改进防碰撞纯ALOHA的matlab仿真算法(Improved anti-collision algorithm for pure ALOHA the matlab simulation)

simulink的仿真有两个阶段：一个为初始化，这个阶段主要是设置一些参数，像系统的输入输出个数、状态初值、采样时间等；第二个阶段就是运行阶段，这个 阶段里要进行计算输出、更新离散状态、计算连续状态等等，这个阶段需要反复运行，直至结束。(simulink simulation has two phases: one for initialization, this stage is mainly to set some parameters, such as the number of input and output system, initial state, the sampling time second stage is the operational phase, the Stages to calculate the output, update the discrete state, continuous calculation of the state, etc., this stage requires repeated runs to the end.)

进行FFT变换，在此基础上作频谱分析、功率谱分析等。(FFT transform, on the basis for spectrum analysis, power spectrum analysis.)

说明：  LZW of black and white images
