摘要
联合战术信息分发系统JTIDS(Joint Tactical Information Distribution System)是一个大容量、高速度、抗干扰、保密、时分多址的信息分发系统,在未来信息化战争中起到了越来越重要的作用。通信可靠性是充分发挥JTIDS系统作用的重要保证,信道编码可以有效提高系统可靠性。为分析信道编码在JTIDS系统中的作用,从CRC、RS编译码原理出发,研究了信号在JTIDS中传输过程,最后运用Simulink软件设计了JTIDS通信系统链路,并对未编码信号、RS编码信号、CRC-RS编码信号在有噪信道中传输的误码性能进行了仿真测试,结果表明采用CRC-RS编码能有效提高JTIDS通信的可靠性。
JTIDS（Joint Tactical Information Distribution System）is a information distribution system of high capacity,high rate,jam-resistance and high security,and would play an important role in the future information warfare.Communication reliability could ensure the operation of JTIDS while channels coding improve the reliability of JTIDS.For analyzing the role of channels coding in JTIDS,the principle of CRC and RS coding technology is given,the transmission of signal in JTIDS discussed,and finally the JTIDS communication system designed with Simulink software.The bit error rates in cases of coding;RS coding of CRC-RS coding are simulated,the simulation results indicate that the CRC-RS coding could obviously improve the reliability of JTIDS communication.
