  • Technique for cell signature determination
    Patent number: 8781467
    Abstract: 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.
