摘要
介绍了CDMA系统中反向链路卷积编码器的原理;介绍了一种基于复杂可编程逻辑器件,利用VHDL硬件描述语言实现IS-95CDMA系统中反向链路卷积编码器的方法,并给出了在MAX+PLUSII软件下的仿真结果。
In this paper, the principle of the eonvolutional codes encoder in modern systems is introduced at first, then a method for realizing convolutional codes encoder in IS - 95 CDMA systems depending on CPLD and VHDL is stated,and the simulation resluts in MAX ＋ PLUSII software are given.
