Dynamic Spectrum Access (DSA) has been proposed as a means of increasing spectrum utilization by sharing between frequency agile and static radios, but the low number of field tests relevant to DoD scenarios has hampered the transition of DSA enabled systems into radio programs of record. This paper details the field testing of multi-transceiver DSA radios operating in the presence of a legacy system...
A RF spectrum survey was conducted during a Navy exercise in the summer of 2013 to characterize the electromagnetic environment of a military surface ship and the associated emissions of complementary ships present during the exercise. The spectrum survey system consists of receiver antennas, a real-time spectrum analyzer, computer and associated instrumentation. The spectrum range from 20 MHz–6000...
Cognitive Radio (CR) with Dynamic Spectrum Access (DSA) is a promising technology to alleviate spectrum shortage problem in wireless communications. Military and commercial interests in the technology are high, to promote greater spectrum efficiency. The CR/DSA radio networking, however, introduces entirely new classes of security threats and providing strong security may prove to be the most difficult...
