| 摘要 |
The invention discloses a method, a receiver and a wireless terminal for measuring an impulse response e.g. in a (W)CDMA terminal having at least two receiving antenna branches with diversity reception. In the method one antenna branch is selected, e.g. by choosing the antenna with a good signal to interference ratio. An impulse response is measured for the selected antenna branch (full IRM) with a searcher. The delays of the propagation paths are estimated by selecting the delay values, whose correlation value exceed a threshold. The impulse response measurement for the other antenna branch is performed only on the selected delay values (reduced IRM) with the searcher. The finger allocations can be done immediately after the corresponding IRM has been measured or alternatively together after the reduced IRM. The invention may be implemented in at least one of a programmable device, dedicated hardware, programmable logic and any other processing device.
