摘要： An apparatus and method are disclosed relating to estimating a delay, and primarily, though not exclusively, to estimating a delay for use in Passive Intermodulation (PIM) cancellation, i.e. for alignment. The method comprises adapting one or more transmit signals within a defined band to improve the autocorrelation properties of the transmit signal. The method may also comprise generating on the basis of at least the transmit signal and a corresponding receive signal a respective passive intermodulation signal comprising a simulated n th order passive intermodulation product, where n is an odd integer greater than two. The method may also comprise correlating the generated passive intermodulation signal with the receive signal to identify a correlation peak, and determining a time offset (t deiay ) to apply to the generated passive intermodulation signal based on the correlation peak.
