GEOMETRY MEASURING METHOD, RADIO RECEIVING DEVICE AND MOBILE STATION DEVICE

PROBLEM TO BE SOLVED: To provide a method for producing, under a propagation environment where multipaths are formed, simply and easily a geometry for facilitating determining which is better to perform RAKE reception for reception signals or to perform adaptive reception by using an adaptive equalizer, an interference canceller or the like. SOLUTION: Interference signal electric power contained in the receiving signal is measured for each path and the interference signal electric power measured for each path is totalized for N paths thereof. Further, interference signal electric power other than that of the paths contained in the receiving signals is measured and its own cell interference signal electric power is calculated by subtracting a total value determined by totalizing the interference signal electric powers of each path for the N paths from a value determined by multiplying the interference signal electric power other than that of the paths by N. Furthermore, a total electric power value of the other cell interference signals and noises is calculated by subtracting aforementioned its own cell interference signal electric power from the interference signal electric power other than that of the paths, thus calculating the geometry by dividing the its own cell interference signal electric power by the total electric power value of the other cell interference signals and noises.
