Cognitive Radio Architecture: The Engineering Foundations of Radio XML

Chapter 7. RADIO KNOWLEDGE

Radio knowledge is the body of knowledge of the world's radio engineers. This body of knowledge continues to expand and to be revised, fueled by $1 trillion per year in related global economic activity. This chapter organizes that knowledge into pairs of <Knowledge/> chunks with a corresponding <Use/> for that chunk. For the full collection of <Knowledge/>—<Use/> pairs see the companion CD-ROM.

RADIO-DOMAIN OVERVIEW

Radio science embraces the many broad classes of radio propagation and signal modalities suggested in Figure 7-1. A few radio bands such as ELF are not listed because there are few classes of transmitter and receiver and the antennas are miles long. In addition, the near-terahertz (THz) bands used in medical research are not listed. Those specialized bands do not benefit much from the technologies of AACR. Commercial, civil, aeronautical, scientific, medical, and military radios employ the bands and modes of the figure.

The types of radio implied in Figure 7-1 suggest the breadth of radio knowledge that must be formalized to enable algorithms of AACRs to be autonomously competent in radio domains. In SDR jargon, a waveform corresponds to an air interface and protocol stack. A radio mode is a set of parameters of the waveform, including the waveform class, allocated RF band, multiple access scheme, channel symbols, timing, framing, and control signals, traffic channels, protocol stack, and the services provided by the mode such as voice, data, ...
