Kalman filter brief code

说明：  利用分布傅里叶方法进行数值仿真，包含损耗、色散、SPM效应。 可以观察脉冲展宽与压缩，光孤子演化。(The distributed Fourier method is used for numerical simulation, including loss, dispersion and SPM effect. We can observe the pulse broadening and compression, and the evolution of optical solitons.)

用matlab编写的一个数字下变频程序，可供参考. (Matlab prepared a digital conversion program is available for reference.)
