DISTANCE ESTIMATION DEVICE, MOBILE TERMINAL, DISTANCE ESTIATION METHOD, AND PROGRAM
A phase rotation amount of each of subcarriers is calculated by calculating a difference between the first phase difference and the second phase difference between consecutive subcarriers included in radio signals, and performing phase addition processing based on the difference. A characteristic co...

| description | A phase rotation amount of each of subcarriers is calculated by calculating a difference between the first phase difference and the second phase difference between consecutive subcarriers included in radio signals, and performing phase addition processing based on the difference. A characteristic coefficient regarding a change rate of the phase rotation amount of each of the subcarriers with respect to a frequency is calculated by performing a linear regression analysis of the relationship between a frequency and the phase rotation amount, and a distance is estimated based on the characteristic coefficient. |
