Cooperative spectrum sensing algorithm based on limiting eigenvalue distribution by Yin MI, Guang-yue LU

“…A novel maximum-minimum eigenvalue (NMME) cooperative spectrum sensing algorithm and threshold decision rule are proposed via analyzing minimum eigenvalue limiting distribution of the covariance matrix of the received signals from multiple cognitive users (CU) by means of latest random matrix theory (RMT).The proposed scheme could not need the prior knowledge of the signal transmitted from primary user (PU) and could effectively overcome the noise uncertainty.At a given probability of false alarm (P<sub>fa</sub>),simulation results show that the proposed scheme can get lower decision threshold and higher probability of detection (P<sub>d</sub>) compared with the original algorithm,and it can also get better detection performance with fewer CU and smaller sample numbers.…”

Full duplex secret transmission scheme based on user cooperation by Xiao-lei KANG, Xin-sheng JI, Lu XIA, Kai-zhi HUANG

“…Full-duplex artificial noise scheme can achieve a limited improvement while the interference power keeps increasing and the full-duplex gain is null.To solve these two problems,a full-duplex secure transmission scheme based on user cooperation was proposed,in which the full-duplex receiver used partial power to send artificial noise,and transmitted the downlink signal by the remaining power to the user who shared the same frequency.In order to maximize the system secrecy rate,the beam vector of the desired signal and the artificial noise were designed.Besides,the optimal power allocation factor was obtained by one-dimensional search simply.Simulation results show that compared with the RS-ref and HD methods,the proposed method can achieve an approximate linear growth in high power and can obtain the full-duplex gain.…”
