摘　　要：介绍了两类具有代表性的高性能非系统前馈卷积码编码器的编码原理及过程,用超高速硬件描述语言VHDL编程实现了这两种编码器,波形仿真及下载到现场可编程门阵列FPGA芯片上运行的结果表明了设计的正确性和实用性。由于该设计具有通用性,此方法能非常方便地用于同类型卷积码编码器的设计,在无线通信领域可发挥重要作用。The encoding theory and process for two kinds of nonsystematic feedforward convolutional coder were introduced. This paper fulfilled the coders by using very high speed integrated circuit hardware description language, the experiment demonstrated the correctness and practicability for this design. The method can be used for the same type of convolutional coder, and will play an important role in the field of wireless communications.
