XG DSA Radio System

摘要

This paper describes the Dynamic Spectrum Access radio system that was built as part of the DARPA XG Program [1]. The DSA system's architecture four principal components (the DSA engine; the environmental sensing (i.e., detection) subsystem; the communications (i.e., radio) subsystem; and a policy module/enforcer) are described. The DSA system's 802.16-based radio hardware is described. One of the field tests related to Group Sensing is described. A companion paper describes the XG DSA Policy software design and field test.
