    • In one embodiment, the present invention is a method for performing incremental preamble detection in a wireless communication network. The method processes non-overlapping chunks of incoming antenna data, where each chunk is smaller than the preamble length, to detect the signature of the transmitted preamble. For each chunk processed, chips of the chunk are correlated with possible signatures employed by the wireless network to update a set of correlation profiles, each profile comprising a plurality of profile values. Further, an intermediate detection is performed by comparing the updated profile values to an intermediate threshold that is also updated for each chunk. Upon receiving the final chunk, the correlation profiles are updated, and a final preamble detection is made by comparing the updated profile values to a final threshold. Detections are performed on an incremental basis to meet latency requirements of the wireless network.
    • 在一个实施例中,本发明是一种用于在无线通信网络中执行增量前导码检测的方法。 该方法处理输入天线数据的不重叠块,其中每个块小于前导码长度,以检测所发送的前导码的签名。 对于处理的每个块,块的码片与由无线网络使用的可能的签名相关联,以更新一组相关轮廓,每个轮廓包括多个轮廓值。 此外,通过将更新的简档值与也为每个块更新的中间阈值进行比较来执行中间检测。 在接收到最后的块之后,更新相关轮廓,并且通过将更新的简档值与最终的阈值进​​行比较来进行最终的前导码检测。 检测是按增量执行的,以满足无线网络的延迟要求。
