Implementation method for heterogeneous network convergence system with reconstruction capacity in cognitive radio

Abstract

The invention discloses an implementation method for a heterogeneous network convergence system with reconstruction capacity in a cognitive radio. The implementation method includes the following steps that (1) a frequency spectrum is scanned; (2) frequency spectrum information is obtained; (3) whether a frequency band allowed to be used can be used directly or not is inspected, and if not, the obtained cognitive information is stored in a knowledge data base; (4) all devices in a network obtain updated information from the data base for decision learning; (5) after learning, respective configuration information of the devices is adjusted to be adaptive to connecting in a new frequency spectrum; (6) after adjustment, whether cognition is success or not is judged, and if the cognition is success, dynamic frequency spectrums are distributed. According to the implementation method for the heterogeneous network convergence system with the reconstruction capacity in the cognitive radio, non-authenticated users and authenticated users can share frequency resources, and therefore the use ratio of the frequency spectrum is improved.

Description

technical field [0001] The invention relates to an implementation method of a heterogeneous network fusion system with reconfiguration capability in a cognitive radio, and belongs to the technical field of communication. Background technique [0002] In the future, wireless communication will develop in the direction of heterogeneity, broadband, and flatness, which will accelerate the growth of demand for wireless frequency resources. However, the spectrum resources assigned to many existing wireless systems are idle to varying degrees in time and space, and the shortage of wireless frequency resources has become a new bottleneck restricting the development of wireless communications in the future. [0003] In the future, the wireless communication frequency band will become more and more tense. Cognitive radio can sense the spectrum, so that cognitive users and authenticated users can share the spectrum without interference, and become an important method to improve spectru...
