INTERFERENCE WAVE POWER MEASUREMENT DEVICE AND INTERFERENCE WAVE POWER MEASUREMENT METHOD, SIR MEASUREMENT DEVICE AND SIR MEASUREMENT METHOD

摘要

PROBLEM TO BE SOLVED: To provide an interference wave power measurement device capable of measuring interference wave power with higher accuracy not only under multipath environment but also under high speed mobile environment.;SOLUTION: An interference wave power measurement device 20 includes: a correlation value calculation part 22 for calculating a correlation value between a received reference signal component and a complex conjugate of a known signal component of the reference signal; a difference correlation value calculation part 25 for calculating a difference correlation value based on a multipath characteristic oriented system and a difference correlation value based on a fast moving characteristic oriented system, based on correlation result data; an interference wave power calculation part 26 for calculating average interference wave power by accumulating a difference correlation value over predetermined times, for each of the multipath characteristic oriented system and the fast moving characteristic oriented system; and a selection part 28 for selecting a smaller value with within the average interference wave power for each of the systems.;COPYRIGHT: (C)2016,JPO&INPIT
