International Telemetering Conference Proceedings / October 29-November 02, 1990 / Riviera Hotel and Convention Center, Las Vegas, Nevada / In this Paper, the time-assisting code techique capable of defeating the repeat jamming is presented. The construction and antijamming performance of this technique are described and analyzed. This technique not only is robust to repeat jamming of Remote Control/Telemetring and Communication Systems, but also is used in multi-address remote control/ telemetring, multi-address communication and radar systems.
