R3-B.2: Advanced Imaging and Detection of Security Threats using Compressive Sensing
نویسنده
چکیده
This year, we have focused on the acceleration of two inverse operators, so that they can be used by the Compressive Sensing (CS) imaging algorithms in the future. In particular, the following activities were performed for this project: 1) Development of a multistatic FFT-based formulation for imaging applications; and 2) Acceleration of the multistatic Inverse Fast Multipole Method (I-FMM) using GPUs. Both techniques are inverse methods; the FFT-based is faster than the I-FMM, however the former is less accurate than the latter. For this reason, the FFT can be used as a coarse-scale imaging algorithm and the I-FMM can be used as a fi ne-scale imaging algorithm.

متن کاملSecure Collaborative Spectrum Sensing in the Presence of Primary User Emulation Attack in Cognitive Radio Networks
Collaborative Spectrum Sensing (CSS) is an effective approach to improve the detection performance in Cognitive Radio (CR) networks. Inherent characteristics of the CR have imposed some additional security threats to the networks. One of the common threats is Primary User Emulation Attack (PUEA). In PUEA, some malicious users try to imitate primary signal characteristics and defraud the CR user...
