本发明涉及到达时间估计。提供了一种聚合或组合多个子信道估计以生成聚合宽频带信道估计的主题系统，相比于能够从各个子信道估计确定的那些到达时间估计，该聚合宽频带信道估计可用于确定更准确的到达时间估计。该主题系统还提供了单个信道或聚合信道上的可用于促进准确的到达时间估计的多路径检测。例如，从多路径检测得出的信息可用于补充和/或增强到达时间估计算法。该主题系统还提供了一种允许设备执行一个或多个信号交换以促进生成聚合宽频带信道估计和/或促进执行多路径检测的探测协议。该协议允许设备在相干时间内在一个或多个信道上执行信号交换，并且还提供安全机制以及故障恢复。 The subject system aggregates, or stitches, multiple component channel estimates to generate an aggregated wideband channel estimate that can be used to determine more accurate time of arrival estimations than those determinable from the individual component channel estimates. The subject system also provides for multipath detection on a single channel or an aggregated channel that may be used to facilitate an accurate time of arrival estimation. For example, information derived from the multipath detection may be used to supplement and/or enhance a time of arrival estimation algorithm. The subject system also provides a sounding protocol that allows devices to perform one or more signal exchanges to facilitate generating the aggregated w
