Abstract

The Joint Tactical Information Distribution System (JTIDS) is the communication terminal of Link-16. In this work, an improvement on the errors-and-erasures decoder (EED) is proposed for the JTIDS receiver to replace the original EED. Based on the analysis of every two adjacent pulses in JTIDS double pulses mode, we determine the current output symbol, and then reduce the symbol error rate, as well as improve the performance of JTIDS receiver in the complex electromagnetic environment. The simulation results show that as the additive white Gaussian noise and pulsed-noise interference exist, the JTIDS receiver with the proposed improved EED is featured with better anti-interference performance.
