Abstract: For use in visible light communication (VLC), synchronization with multiple topology support while transmitting an extended preamble includes transmitting a two-part preamble sequence. The preamble sequence includes one or more repetitions of a fast locking pattern (FLP) configured to be used clock synchronization, and one or more repetitions of a topology dependent pattern (TDP) configured to be used to distinguish a plurality of VLC topologies. The method for transmitting an extended preamble includes generating an extended preamble and transmitting the extended preamble during a receive or idle mode for maintaining visibility support and for better synchronization performance.
Abstract translation: 为了在可见光通信（VLC）中使用，在发送扩展前同步码时与多个拓扑支持同步包括发送两部分的前导码序列。 前导序列包括配置为使用时钟同步的快速锁定模式（FLP）的一个或多个重复，以及被配置为用于区分多个VLC拓扑的拓扑依赖模式（TDP）的一个或多个重复。 用于发送扩展前同步码的方法包括在接收或空闲模式期间生成扩展前导码并发送扩展前同步码，以便维持可视性支持和更好的同步性能。
