Abstract :
Embedded cyclostationary signature (ECS) was recently developed as a useful tool for facilitating detection, classification, frequency acquisition and spectrum rendezvous for wireless devices or networks. In this paper, we present a novel technique for conveying extended information on ECS in multi-carrier signals. The extended information may include device/network identity, geo-location data and spectrum allocation, etc. In this way, the proposed technique can greatly increase the amount of information which can be obtained using spectrum sensing. This can facilitate the coordination and coexistence among heterogeneous wireless devices/networks that operate in complex, dynamic radio environments. To evaluate the feasibility of the proposed technique, we use both simulation and measurement with real-world RF signals. The results from simulation and measurement match well to each other.
