在数据复用系统中，系统的帧同步搜索时间的长短和搜索方法实现的难易是衡量系统的数据复用方案和同步搜索性能优劣的重要参数。对帧同步码分散插入的复用系统，通常有串行搜索和并行搜索两种方法，但前者的搜索时间较长，后者的实现又较为复杂。现介绍一种新同步搜索方案──定位搜索法，该方案具有搜索时间短、实现方便的优点，适用于软件实现的帧码分散插入的复用方案的同步过程。同时给出了实例。
In the data multiplexing system, the length of the frame synchronization search time and the difficulty of the search method are important parameters to measure the system data reuse scheme and the performance of synchronous search. There are two methods of serial search and parallel search for the multiplexed system in which the frame synchronization code is dispersedly inserted. However, the former has a longer search time and the latter has more complicated implementation. This paper presents a new synchronization search scheme ─ ─ location search method, which has the advantages of short searching time and convenient implementation, and is suitable for the synchronization process of the multiplexed scheme of frame-code decentralized insertion implemented by software. At the same time give examples.
