【摘要】 采用现场可编程门阵列FPGA技术实现数字信号处理,可以很好地解决并行性、可配置性和速度问题。循环码是线性分组纠错码的一个子集,它具有防止突发错误的保护功能。提出了采用硬件描述语言进行设计输入的优点,给出了基于FPGA的一种系统循环码、编码器、译码器,以及m序列发生器的实现办法。更多还原

【Abstract】 The implementation of digital signal processing by using Field Programmable Gate Array(FPGA)can solve problems including parallel architecture,configurationality and speed.Cyclical code is a kind of liner block correct codes,which can prevent random errors.By using VHDL as the inputted language,the paper gives the implementation of the coder,decoder of a cyclical code and a m_sequence generator based on FPGA.更多还原
