Abstract
A cognitive radio communication device including at least two radio frequency (RF) chains is provided. In order to perform a feature detection, the cognitive radio frequency device may reduce or eliminate a quiet time where a data communication is suspended using the at least two RF chains. While one RF chain performs the feature detection, another RF chain may perform the data communication.
Claims12
A cognitive radio communication device comprising:
- a first radio frequency chain comprising a data communication unit to communicate in an in-band and an energy detector to detect an energy of a received signal in the in-band;
- and
- a second radio frequency chain comprising a feature detector to perform a feature detection of the received signal in the in-band.
