报告简介

 

报告：

Signal detection and RF parameter estimation have received great interest in recent years due to the need for spectrum sensing in rapidly growing cognitive radio and cyber security research. In most conventional signal detection and RF parameter estimation work, the target signal is often assumed to be a single primary user signal without overlap in spectrum with other signals. However, in a spectrally congested environment or a spectrally contested environment which often occurs in cyber security applications, multiple signals are often mixed together with significant overlap in spectrum. In this talk, we present our recent work on the feasibility of using a second order spectrum correlation function (SCF) cyclostationary feature to perform mixed signal detection in spectrally congested environment. We also evaluate the detection and estimation performance of the proposed algorithm in various channel conditions and signal mixture scenarios. Additionally, we use software defined radio to implement and demonstrate our cyclostationary analysis based mixed signal detection algorithms.
