3.2.1 iCR Functional Component Architecture

The SDR components and the related cognitive components of iCR appear in Figure 3.1. The cognition components describe the SDR in Radio XML so that the can know that it is a radio and that its goal is to achieve high QoI tailored to its own users. RXML intelligence includes a priori radio background and user stereotypes as well as knowledge of RF and space time perceived and experienced. This includes both structured reasoning with iCR peers and CWNs, and ad hoc reasoning with users, all the while learning from experience.

Figure 3.1: The cognitive radio architecture augments software-defined radio with computational intelligence and learning capacity.

The detailed allocation of functions to components with interfaces among the components requires closer consideration of the SDR component as the foundation of CRA.

3.2.2 SDR Components

SDRs include a hardware platform with RF access and computational resources, plus at least one software-defined personality. The SDR Forum has defined its Software Communications Architecture (SCA) and the Object Management Group (OMG) has defined its Software Radio Architecture (SRA), similar fine-grain architecture constructs enabling...
