    • Described herein are techniques related to data communications using a data packet having at least one frame with a preamble for use over media having a high degree of non-stationary noise (e.g., impulsive noise). The described techniques employ a preamble with a structure having multiple transitions between the preamble sections. Each transition indicates the start of the upcoming frame. With the techniques described herein, if noise damages the transitions between such sections beyond recognition, the receiver can still determine the frame start time from the one or more of the undamaged transitions. Thus, the robustness of communications via the noisy media is significantly increased. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
    • 这里描述了与使用具有至少一个帧的数据分组的数据分组相关的数据通信的技术,前导码用于具有高度非平稳噪声(例如脉冲噪声)的介质。 所描述的技术采用具有在前导码部分之间具有多个转换的结构的前同步码。 每个转换指示即将到来的帧的开始。 利用本文描述的技术,如果噪声破坏了这些部分之间的转换超过识别,则接收机仍然可以从一个或多个未损坏的转变确定帧开始时间。 因此,通过噪声介质的通信的鲁棒性显着增加。 提交本摘要的理解是,它不会用于解释或限制权利要求的范围或含义。
