串行编码检测器的原理及其CPLD硬件实现

Serial Code Detector Design and Implementation with CPLD

串行编码检测技术是CDMA等现代通信技术的重要内容之一,因其灵活性和实用性,在各种领域中都有广泛应用。本文详细介绍了串行编码检测器的工作原理,并以基于状态机的状态迁移法具体讨论了串行编码检测器的分析手段、设计方法、注意事项。最后给出了使用CPLD器件完成的一种串行编码检测器的具体实现,并添附ABEL-HDL语言源代码。本文对同类设计具有一定的理论和实践参考价值。

Serial Code Detector is one of important contents in modem communication technology such as CDMA, as well as it is very popular in many fields for its flexibility and usability. This article introduces the principle of serial code detector in detail, discusses its analysis methods, design skills, precautions. At last, based on state machine model and enclosing ABEL-HDL source code, a concrete example implemented with CPLD is provided. This article is valuable to the similar design in both theory and practice.
