摘要
数字信号在传输过程中受到干扰的影响,降低了其传输的可靠性,线性分组码作为一种常用的信道编码,在通信传输系统中应用广泛。在对线性分组码的编译码规则研究基础上,讨论了生成矩阵、监督矩阵与错误图样集之间的关系,在Max+PlusⅡ开发环境中,用VHDL语言设计线性分组码编译码器,对其各项设计功能进行了仿真和验证。结果表明,该设计正确,其功能符合线性分组码编译码器的要求。
The interference reduces transmission reliability when digital signal is transmissed in signal path.Linear block code is widely used in communication transmission system as a common channel coding.The generating matrix,monitoring matrix and the relationship between the error pattern sets are discussed based on the coding and decoding rules of linear block codes.The Max+Plus Ⅱ software simulation and verification shows that its function comforms to the linear block code encoding and decoding device requirements.
