第四代移动通信music算法，是我很辛苦才弄出来的。希望可以喝大家交流(Fourth-generation mobile communication music algorithm, it is very hard to get me out. Hope that we can drink to facilitate the exchange of)

A demo showing how work the basic active conter method (snakes).

把轨道根数转移到对应的状态向量，在轨道中很常用。(The orbital elements are transferred to the state vector)

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.
