Systems-Level Architecture Analysis The objective of this chapter is to give the reader practice in addressing software-radio architecture issues at the systems level. The study of systemslevel software-radio architecture is first motivated with a realistic case study. The case study includes the critical parameters of most radio architectures. The analysis focuses on those aspects that are significant for software-radio architecture. The balance of the chapter develops the issues raised in the case study. I.

DISASTER-RELIEF CASE STUDY This case study considers a mobile communications capability for disaster relief. The capability includes mobile infrastructure mobile nodes and handsets. The design emphasis is on defining an open architecture for the infrastructure. Architecture defines components at such a high level of abstraction that one needs a concrete sequence of specific implementations20 in order to assess the contributions of the architecture. Architecture insight seems to develop with implementation practice. It seems to take a half-dozen design and implementation cycles to develop the intuition necessary to make strong contributions to architecture. This case study therefore should be designed and redesigned by the serious student as the text progresses. A. Scenario The case study addresses the fact that medium-sized urban areas may be decimated by a natural disaster. As illustrated in Figure 4-1 the disaster area may be largely obliterated. The destruction of the Holmstead area in South Florida by hurricane Andrew is a practical example of such a disaster. The populace has enjoyed the use of cellular telephone but the disaster is assumed to have wiped out the wireless network. At the periphery of the disaster area connections are available via fiber and or .
