IEEE Std 1900.1-2019 pdf download – IEEE Standard for Definitions and Concepts for Dynamic Spectrum Access: Terminology Relating to Emerging Wireless Networks, System Functionality, and Spectrum Management
This revision to IEEE Std 1900.1TM-2008 adds additional definitions, modifies existing definitions, and removes outdated definitions; it updates the auxiliary text and informative annexes to reflect new concepts and developmen ts in advanced radio systems; in troduces a tax onomy of terms which depicts relationships between definitions and concepts, and updates the document structure to align revised definitions, concepts, and relations hips between ter ms and definitions.
3.5 Intelligent radio A type of cognitive radio that is capable of machine learning. See also: machine learning. NOTE-. Intelligent radios are radio is considered to be a subset of soft ware- con trolled radios fadie. This dependency occurs because the definition for machine learning in 8.63 requires an intelligent radio to adapt the decision-making process, which implies dynamic reprogramming. The reprogramming of radio control would not be possible unless the radio were also software con trolled. However, such a radio need not be software defined since it would be possible for an intelligent radio to use software control to adapt the decision -making process controling how or when a fixed set of hardw are- defined physical layer implemen tations are used. A software- defined, software-con trolled intelligent radio would have the additional ability to chan ge the physical layer implemen tation dynamically under software control. 3.6 Policy-based radio A type of radio in which the behavior of communications systems is governed by a policy -based control mechanism. See also: policy-based control mechanism.
NOTE 1- -Radios in which the communications functions are implemented in software are considered hardware radios for regulatory purposes if the regulated emission or reception parameters cannot be dhanged in the field, post manufacture, without physically modifying the device. However, a device having regulated parameters that can be changed without physical modification is considered a software-defined radio, even if such a change requires specialized equipment or proprietary procedures. NOTE 2- This term represents an idealized abstraction that is useful in designating categories of radio devices (e.g., hardware radio, software-defined radio, and cognitive radio) to which certain regulatory provisions or functional capabilities may apply. The term is also useful in describing the general evolution in the software reconfigurability of radio devices with hardware radio not being software reconfigurable and software -defined radio being software reconfigurable. Software-defined radios include software- reconfigurable hardware such as microprocessors, digital signal processors, . and field-programmable gate arrays that are used with software to implement communications functions. The degree of software reconfigurability will depend on the radio implementation.
