代码说明:

  傅里叶变换能将满足一定条件的某个函数表示成三角函数(正弦和/或余弦函数)或者它们的积分的线性组合(Fourier transform to meet certain conditions can be expressed as a function of trigonometric functions (sine and/or cosine functions) or their linear combination of the integral)

    数据处理及误差分析采用了matlab软件来实现,它的界面虽然没有VB等直观简便,但其可调用的函数多,实现起来比较方便,程序中已经实现的功能有: (1)求算术平均值; (2)求残余误差(绝对误差); (3)求标准差; (4)判断粗大误差,如果发现粗大误差,剔除粗大误差后再进行计算; (5)判断数据是否具有线性误差或者周期性误差。 (Data processing and error analysis using matlab software to achieve, its intuitive interface, while not VB so simple, but its function can be called many realize it was easier, the program has been implemented features are: (1) Find the arithmetic mean (2) Find the residual error (absolute error) (3) Find the standard deviation (4) to determine gross error, if found to gross error, calculated after excluding gross error (5) to determine whether data has linear error or Periodic error.)

    用rayleighchan 函数仿真时要注意最后要做相位补偿(此问题是导师发现的) 程序步骤: ~产生随机序列 ~产生瑞利信道 ~调制 ~记忆信道特征 ~信号通过信道 ~相位补偿 ~加高斯噪声 ~解调 ~计算仿真误比特率 ~计算理论误比特率 ~不同颜色画出误比特率曲线对比(Function Simulation with rayleighchan last thing to note when the phase compensation (this issue is found mentor) program steps: ~ ~ generated random sequence modulation in Rayleigh Road, ~ ~ ~ memory characteristics of the signal channel by channel ~ ~ plus Gaussian noise phase compensation ~ ~ demodulation bit error rate calculation simulation of bit error rate calculation theory ~ ~ different colors to draw curves of bit error rate)
