| Abstract: | This paper presents the basic characteristics of chaotic code, and puts forward proposal of applying the chaotic code for the TT＆C （Telemetry, Tracking and Command） system as a spread-spectrum code. The structure of spread-spectrum TT＆C system and key technologies are discussed to prove the feasibility of spread-spectrum TT＆C system based on chaotic code. The study shows that the chaotic code are more excellent than traditional spread spectrum code in the encryption and anti-MAI （Multiple Access Interference）. |
