What Does Cognitive Radio Mean?
Cognitive radio is a special kind of smart radio transceiver hardware that automatically detects all available wireless channels on a spectrum, facilitating changes to its reception or transmission parameters, which allows the concurrent transmission of multiple additional wireless communications in a location's given spectrum. This process is known as dynamic spectrum management.Cognitive radio's main purpose is to detect and share unused spectrum with other systems without creating harmful interference. This includes spectrum management, or finding the best available spectrum to meet user communication requirements.
