Abstract
A receiving apparatus includes a receiving portion to receive a radio signal generated based on one baseband signal of a baseband signal having a prescribed frequency band and a baseband signal having a partial frequency band being a part of the prescribed frequency band, a signal processing portion to generate the baseband signal by converting a frequency of the radio signal, a filter portion to output a plurality of partial signals, each having a frequency component of each partial frequency band extracted from the baseband signal generated by the signal processing portion, and an analysis portion to analyze characteristics of each partial signal of the plurality of partial signals output from the filter portion.
Claims10
A receiving apparatus, comprising:
- a receiving portion to receive a radio signal generated based on one baseband signal of a baseband signal having a prescribed frequency band and a baseband signal having a partial frequency band being a part of the prescribed frequency band;
- a signal processing portion to generate the baseband signal by converting a frequency of the radio signal;
- a filter portion to output a plurality of partial signals, each having a frequency component of each partial frequency band extracted from the baseband signal generated by the signal processing portion;
- an analysis portion to analyze characteristics of each partial signal of the plurality of partial signals output from the filter portion;
- and
- a determination portion to determine that the baseband signal generated by the signal processing portion is a baseband signal having the prescribed frequency band if a difference in demodulation information of the plurality of partial signals analyzed by the analysis portion is within a setting range.
A program for causing a computer to serve as a receiving apparatus comprising:
- a receiving portion to receive a radio signal generated based on one baseband signal of a baseband signal having a prescribed frequency band and a baseband signal having a partial frequency band being a part of the prescribed frequency band;
