interference wave power measuring device and interference wave power measurement methods and SIR measuring device and SIR measuring method

摘要

Disclosed is added under a multipath environment and provides an interference signal power measuring device for the interference power can be measured with higher accuracy than the conventional under high-speed moving environment. An interference wave power measuring device 20 includes a correlation value calculation unit 22 for calculating a correlation value between the complex conjugate of the received reference signal component which of the known signal component, the multi-path characteristics based on the data of the correlation result the difference correlation value calculation unit 25 to calculate the respective difference correlation value by the difference correlation value and the high-speed movement characteristic consideration method by taking into account system, the difference correlation value due to multipath characteristics consideration method or the high-speed movement characteristic consideration method only each predetermined number integration It is provided and the interference wave power calculation unit 26 which calculates for each method the average interference wave power by, a selection unit 28 to select the value of people power is low among the average interference wave power of each scheme,BACKGROUND 1
