Spectrum sensing algorithm based on stochastic resonance and non-central F-distribution
Published 2023-01-01“…To solve the problem that the detection probability of the spectrum sensing algorithm is low and the number of samples required for detection is large at low signal-to-noise ratio (SNR), a spectrum sensing algorithm based on stochastic resonance and non-central F-distribution (SRNF) was proposed.By introducing direct-current stochastic resonance noise, the system model of SRNF was established, and the expression of test statistic, false alarm probability and detection probability, and the expression of decision threshold obeying non-central F-distribution were deduced, and the optimal stochastic resonance noise parameter was solved by numerical method.The simulation results show that the detection performance of the proposed SRNF algorithm is better than that of energy detection (ED) algorithm and blind spectrum sensing based on F-distribution (BSF) algorithm at a low SNR.When the false alarm probability is 5%, the SNR is -12 dB, and the number of samples is 200, the detection probability of the proposed algorithm is 95%, which is 34% and 67% higher than BSF algorithm and ED algorithm, respectively.When the SNR is -12 dB, and the detection probability reaches 95%, the number of samples required by the proposed algorithm is 210, which saves 340 samples compared to the BSF algorithm.Furthermore, the proposed algorithm is less affected by noise uncertainty than ED algorithm.…”

Adaptive channel status based access class barring scheme for traffic emergency communication
Published 2022-01-01“…In high-density cellular vehicle-to-everything (C-V2X), effective massive access method of cluster communications is the basis to assure the performance index for different services and enhance the spectrum efficiency under limited resource.An improved access class barring (ACB) scheme was proposed using channel status information based on computing power of communication terminal in C-V2X.The base station estimated the communication density within its cover range, generated the ACB factor using the communication density, and broadcasted the ACB.According to signal to interference plus noise ratio (SINR) and ACB factor of the received broadcast signal, the vehicular communication terminal computed the access probability, and compared with ACB factor.When the access probability was more than the ACB factor, the terminal selected a preamble randomly from the preamble pool with the probability which equal to the access probability or one.The terminal transmited the selected preamble to the base station for finishing the access program.The simulation results show that the scheme proposed has 5%~20% advantage over S-Aloha and machine to machine opportunistic splitting algorithm (M2M-OSA) schemes in average access collision probability.It reduces the average access delay effectively.…”

Opportunistic cooperative spectrum sensing based on eigenvalue ratio of random matrix
Published 2020-02-01“…To overcome the deficiencies of low detection probability of traditional spectrum sensing,an EROC spectrum sensing algorithm based on the eigenvalue ratio of a random matrix was proposed.Based on the random detection theory,it used double thresholds and opportunistic cooperation to improve of traditional maximum and minimum eigenvalue (MME) algorithm,and it retained the advantages of the traditional energy detection algorithm.Moreover,on the premise of known false alarm probability,the decision threshold was deduced,and the odd-even slot division was used to effectively realize opportunistic cooperation in reception.Simulation results show that the proposed spectrum sensing algorithm has higher detection probability than MME algorithms in case of low signal-to-noise ratio and low false alarm probability.Therefore,it is suitable for application in wireless communications with deteriorate transmission channels.…”
