    • A technique for cell signature determination in a cellular communication network is described. A method implementation of this technique comprises the steps of providing a set of cell signature hypotheses (d(n)), each cell signature hypothesis including a first partial hypothesis (d(2n)) and a second partial hypothesis (d(2n+1)), receiving a signal (X(n)) carrying a cell signature, the signal (X(n)) including a first partial signal (X(2n)) and a second partial signal (X(2n+1)), correlating the first partial signal (X(2n)) with each first partial hypothesis (d(2n)) to determine a first correlation result for each cell signature hypothesis, correlating the second partial signal (X(2n+1)) with each second partial hypothesis (d(2n+1)) to determine a second correlation result for each cell signature hypothesis, and determining the cell signature based on the correlation results including discarding a given cell signature hypothesis based on an analysis of a first magnitude of the first correlation result associated with the given cell signature hypothesis and a second magnitude of the second correlation result associated with the given cell signature hypothesis.

    • A technique for cell signature determination in a cellular communication network is provided. A method implementation of this technique comprises the steps of providing a set of hypothesis signals, each hypothesis signal including a signature hypothesis, receiving a composite signal including a first signal portion carrying a first signature from a first cell and a second signal portion carrying a second signature from a second cell, wherein the first signal portion and the second signal portion overlap at least partially in time, and obtaining a correlation result by correlating the composite signal with each hypothesis signal. After the first signature has been determined, a set of phantom signatures associated with the first signature is provided. The phantom signatures represent artifacts from the first signal portion in the correlation result. Finally, the second signature is determined based on the correlation result taking into account the set of phantom signatures associated with the first signature.
    • 提供了一种在蜂窝通信网络中进行小区签名确定的技术。 该技术的方法实现包括以下步骤:提供一组假设信号,每个假设信号包括签名假设,接收包括携带来自第一小区的第一签名的第一信号部分和携带第二信号的第二信号部分的复合信号 签名,其中所述第一信号部分和所述第二信号部分至少部分地在时间上重叠,并且通过将所述复合信号与每个假设信号相关来获得相关结果。 在确定了第一签名之后,提供了与第一签名相关联的一组幻影签名。 幻影签名代表相关结果中来自第一信号部分的伪影。 最后,基于与第一个签名相关联的一组幻影签名的相关结果来确定第二个签名。
