摘要
差错控制编码在移动通信系统中应用广泛,可以克服由于移动传播环境引起的波形变坏或随机的差错.基于VHDL语言,设计了一个CRC加卷积编码系统,硬件采用一片EPM7128SLC84-15芯片,软件采用VHDL语言编程,该系统结构紧凑,体积小,功能稳定可靠.
Err control encoding has a variety of applications in mobile communication system.It can overcome wave distortion or random err that caused by the bad spread environment.In this paper,a CRC and convolution encoding system is introduced,of which the hardware circuit is realized by utilizing complex programmable device（CPLD）,and software program written by VHDL language.The system construction is compact and requires much less space.
