说明：  利用matlab仿真软件，实现8QAM调制。在实现时采用正交调幅的方式,某星座点在I坐标上的投影去调制同相载波的幅度,在Q坐标上的投影去调制正交载波的幅度,然后将2个调幅信号相加就是所需的调相信号。(Use of matlab simulation software to achieve 8QAM modulation. In achieving the adoption of quadrature amplitude modulation means of a constellation in the I coordinates of the projection to the modulation of the amplitude-phase carrier, in the Q coordinates of the projection to the range of carrier orthogonal modulation, and then the sum of two AM signals is the required phase modulation signal.)

LDA的matlab实现，得出alpaha和beta的值(the procedure to implement Latent Dirichlet Allocation ,the end of this procedure is the value of alpha and beta.)

素数的判定，miller-rabin，sol-str,leman,fermat等。都可以运行，下完自后自己稍微改改就可以用。(Primes judgment, miller-rabin, sol-str, leman, fermat so on. Can run is finished after their own little changed since it can be used.)

直线阵自然指向性仿真,先根据设定的角频率仿真单频信号A sin(ωt)；再根据阵元间距、入射角度计算得各阵元相对参考阵元接收的信号的时延 τ (dsin(θ))/c。 假设等间隔N基元线阵，入射信号是平面波，那么阵元输出信号为：S_n (t) A sin(ωt+nφ)；其中 φ 2πfτ 为相邻阵元接收信号间的相位差；再将基阵各元输出求和，取最大值max,就得到输出幅度；以入射角为横坐标，幅度为纵坐标作图得直线阵自然指向性。 (Linear array directivity simulation)
