TDC(Transform Domain Communication变换域通信)技术采用的是躲避式抗干扰方式。在通信中实施干扰躲避,可以有效地避免或降低干扰对通信的影响。文中首先对TDC技术进行了简要介绍,对这一抗干扰技术应用于静止卫星通信系统的可行性和应用方式进行了探讨。仿真表明基于TDC技术的静止卫星通信系统具有抗多种干扰的能力,但由于通信时延,在干扰频率发生变化时,通信的抗干扰能力有所下降。
TDC (Transform Domain Communication) communication technology is the use of evasive anti-jamming mode. In the communication interference avoidance, can effectively avoid or reduce the interference on the communication. Firstly, a brief introduction of TDC technology is introduced in this paper, and the feasibility and application of this anti-interference technology in the stationary satellite communication system are discussed. The simulation shows that the static satellite communication system based on TDC technology has the ability to resist many kinds of interferences. However, due to the communication delay, the anti-interference ability of communication decreases when the interference frequency changes.
