Abstract:
The present invention is a device which, when a second wireless system shares the use of a frequency which is allocated to a first wireless system, estimates receiving power when a second wireless signal which is transmitted from a transmission station of the second wireless system is received at a receiving station of the first wireless system. The receiving power estimation device comprises a correction means for correcting a receiving power estimate value of the second wireless signal at the first wireless system receiving station which is computed using an estimate value of path loss from the second wireless system transmission station to the first wireless system receiving station, said correction using a receiving power measurement value of the second wireless signal which is measured in a transmission station periphery sensor station which is a sensor station which is located in the periphery of the second wireless system transmission station.
