PROBLEM TO BE SOLVED: To provide a technology for recognizing the influence of interference regardless of whether timing synchronization is established or not.SOLUTION: A radio section 22 inputs the signal of a time domain. An FFT section 42 converts the input signal of the time domain to the signal of a frequency domain. A detection section 48 detects whether reception power of the signal of the frequency domain has an upward tendency from one frequency side of the signal of the frequency domain to the other frequency side. An estimation section 50 estimates presence of interference power in the other frequency side when detecting the upward tendency. |
