چکیده
Abstract – Performance degradation of an analog FM and PAL-G signal due to Spread Spectrum (SS) interference is investigated. An analytical expression between RF TV protection ratio (CIR) and baseband unweighted Signal-toNoise ratio (SNRV), for co-channel spread spectrum and noise interference, is derived. Also, we expressed the audio frequency signal-to-noise ratio (AF SNR) output due to SS overlay for various types of spreading scenarios and for different carrier frequency differences (Δf).

Spectrum Sensing Data Falsification Attack in Cognitive Radio Networks: An Analytical Model for Evaluation and Mitigation of Performance Degradation
Cognitive Radio (CR) networks enable dynamic spectrum access and can significantly improve spectral efficiency. Cooperative Spectrum Sensing (CSS) exploits the spatial diversity between CR users to increase sensing accuracy. However, in a realistic scenario, the trustworthy of CSS is vulnerable to Spectrum Sensing Data Falsification (SSDF) attack. In an SSDF attack, some malicious CR users deli...

This study presents a full-duplex Radio-over-Fiber (RoF) system providing the users' wireless access with a bit rate of 10 Gbps over 40 GHz radio carrier. This system can be used in a centralized radio access network (C-RAN) architecture because we provide a fully analog front haul link between central station and base station. We can consider it as infrastructure between remote radio heads (RR...
