摘要
论述了在数字有线电视系统中的一种用于包同步提取和错误检测的方法,此方法基于一类线性分组码,其一致校验结构源于本原多项式产生的PN伪随机序列,其一致校验运算可以用FIR滤波器简单实现。
This paper describes a method used for packet synchronization and error detection in the synchronous digital cable television system The method relies upon a class of linear block codes whose parity check structure is based on a pseudonoise sequence generated by a primitive polynomial This structure allows for the computationally efficient implementation of the parity check by FIR filter
