| 摘 要： | 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.

| Abstract: | In the technology of TDC (Transform domain communication), the method of interference avoidance is used. The affection of interference to communication is reduced or avoided by applying the method of interference avoidance in communication system. This paper first briefs the TDCS technology, then, the feasibility and applications of the TDC technology in satellite communication system are discussed. Simulation indicates that the synchronous satellite communication system based on the TDC technology has the ... |
