幻灯片课件，详细的介绍了用matlab进行绘图的方法，比较基础，建议初学者好好看看，很有用。(Courseware slides and detailed introduction to using matlab graphics methods, comparative basis, it is recommended for beginners a good look at, very useful.)

Spread spectrum merupakan sistem dimana sinyal yang dikirimkan memiliki bandwidth yang jauh lebih lebar daripada bandwidth sinyal informasinya sendiri. Proses pelebaran bandwidth sinyal informasi ini dilakukan pada sisi pengirim dan disebut spreading. Sebaliknya, proses penyempitan kembali bandwidth sinyal informasi dilakukan di sisi penerima, dan disebut despreading. Pada gambar 1 berikut menunjukkan proses yang terjadi pada sistem spread spectrum.

此程序是粒子滤波和扩展卡尔曼滤波器的比较，具有很强的针对性(This procedure is the comparison of particle filtering and extended Kalman filter, is highly targeted)
