| 摘要: |
| 联合战术信息分发系统(Joint Tactical Information Distribution System，简称JTIDS)采用组合调制体制和多层编码体系保证报文传输的可靠性。分析了JTIDS数据链在莱斯衰落信道环境下的抗干扰性能，并通过仿真分析了该系统在部分频带干扰下的符号误码率和报文丢失率。仿真结果显示，由于JTIDS系统将RS编码、交织等多种编码技术和DS/FFH MSK调制技术相结合，使其在复杂信道环境下保持较低的符号误码率及报文丢失率，满足数据链报文传输可靠性的要求。 |

| Abstract: |
| The combined modulation methods as well as various encoding methods adopted in Joint Tactical Information Distribution System (JTIDS) guaranteed the message transmission reliability. The anti-jamming performance of JTIDS on rice fading channel is analyzed; the symbol error rate and the message discarded rate of the system in partial band noise interference are derived by simulation. The simulation result shows that various anti-jamming technology such as RS encoding, and Interleaving and DS/FFH MSK modulation combined in JTIDS can improve the performance of data link communication so much that a lower symbol error rate and message discarded rate can be obtained in complex channel environment and the requirement of message transmission reliability is satisfied. |
