ABSTRACT:
A signal frequency band detection device is disclosed that is able to separately handle plural co-existing signals, and able to separately detect frequency bands used for transmission of these co-existing signals. The signal frequency band detection device includes a signal decomposition unit that decomposes a received signal into plural signal components with frequency bands of the signal components at least partially overlapping each other; and a frequency band detection unit that, based on respective electrical powers of the signal components, detects the respective frequency bands of the signal components.
