Abstract: Provided are a receiving device, a receiving method, and a computer program capable of more reliably ascertaining the number and power of transmitting antennas so as to more accurately find a base station. A first power of a first signal transmitted from a first transmitting antenna and a second power of a second signal transmitted from a second transmitting antenna are measured, and a determination is made as to whether the ratio of the first power and the second power is larger than a predetermined threshold value. When a determination is made that the ratio of the first power and the second power is larger than the threshold value, a presumption is made that the number of transmitting antennas is two.
