摘　　要：交织技术能够有效地实现随机性编译码的思想,将其应用到Turbo码中,结合其他的一些技术（如迭代译码、软判决技术等）,可使通信系统获得接近Shannon理论极限的性能.将交织技术引入联合编译码,并结合信源和信道的转移特性,优化联合编译码的译码方式.仿真结果表明,引入交织技术可在不增加码率的情况下有效克服突发错误带来的影响.The interleaving technology can realize random coding, when used in Turbo codes. It can help communication system to achieve Shannon Limits combining with other advanced technologies such as iterative decoding and soft-decision algorithm. The paper introduces interleaving technology into joint source channel coding （JSCC） system, and optimize JSCC decoding method combing with source and channel transformations. The simulation results prove that the introduction of interleaving technology can eliminate the effects from burst errors without the increase of coding rate.
