Cognitive Radio Architecture: The Engineering Foundations of Radio XML

Chapter 8. IMPLEMENTING RADIO-DOMAIN SKILLS

This chapter develops software techniques for using the radio-domain knowledge of the last chapter by a suite of algorithms organized into a CRA for interactive and autonomous realization of the use cases.

The design principle for AACR, for practical engineering applications(i.e., without self-modification learning), is as follows:

AACR Radio Knowledge Exploitation Strategy

An AACR shall optimize choice of its own radio band-mode and network for the user(s) fine-tuning the air interface, network, and computational resources better than the best human radio operator.

Thus, the emphasis when referring to AACR is the optimization of existing SDR personalities with respect to the situation at hand reflected in the RF environment and the user's specific communications needs. The design principles for iCR research are more aggressive, focused on realizing more of the self-modification potential of AML in iCR:

iCR Knowledge Exploitation Strategy

An iCR exhibits better performance than a radio engineer, learning from experience by exploring alternatives both physically and via simulation, suggesting actions for users, cooperating with other iCRs and creating new SDR personalities on the fly that meet the needs of the use case better than any one band, mode, network, or parameter setting alone.

AACR may learn radio knowledge by being told by a trusted authority, just as a SDR can be enhanced by download. Subsequently, they will contribute to the CWN knowledge ...
