| 摘 要： | 采用交织技术使连续的突发错误分散，并转换为随机错误，可以纠正数据在信道传输过程中的成群突发错误。在分析TETRA数字集群通信系统语音信道编码结构和流程的基础上，基于FPGA技术的采用块内交织方法的交织器，提高了整个通信系统的可靠性。利用QuartusⅡ对其进行时序仿真分析，结果表明了该实现方案的正确性和可行性。

| Abstract: | The adoption of the interleaving method to scatter the series burst-errors and transfer them into random errors permits the correction of the burst-errors due to the burst interference of data in the course of transference of data in channel. This paper, combined with the analysis of the voice channel coding structure and procedure of the system, introduces a new FPGA-based method to realize the interleaving of system and improve the dependability of the whole communication system. The timing simulation analysis with Quartus II verifies the accuracy and feasibility of this new method. |
