摘要
介绍了HDB3编解码的原理和方法 ,给出了用CPLD(ComplexProgrammableLogicDevice)实现E1信号HDB3编解码的方法 ,同时给出了它的实现原理图 。
The principle and method of HDB3,which is widely used in the E1transmission,are discussed in deˉtail in this paper.And the coding/decoding implementation of the HDB3signal using CPLD device is presented specifically.A practical implementation using the XILINX CPLD XC9500device is described in the last part.
