Spectrum sensing algorithm based on symmetry of cyclic spectral correlation by Yu-long GAO, Yan-ping CHEN, Xiu-zhi GUAN, Zhong-zhao ZHANG, Xue-jun SHA

“…In response to the shortcoming of conventional algorithms,modified SSCA was exploited to calculate the cyclic spectral correlation of received signal for decreasing the computational complexity.Symmetry of cyclic spectral correlation (CSC) was used to detect the idle spectrum,criteria and method of selecting and judging symmetry were proposed.Conventional binary hypothesis condition was translated to concrete value according to symmetry.In order to eliminate the effect of interference and noise,non-zero cyclic frequencies were selected.Finally,the performance of the presented algorithm was compared with the conventional algorithms by virtue of simulation.Simulation results proved the correctness and the superiority of new algorithms.Using symmetry improves the successful detection probability for low SNR and reduces the computational complexity.…”

Using idle TDMA slots for retransmitting packets cooperatively in VANET by Zhen CHEN, Jiang-hong HAN, Yong YANG, Zheng-yu LIU, Yang LU

“…The distributed TDMA approach for VANET dose not take advantage of idle slots,failing to effectively utilize radio resources.A retransmission method for medium access control was proposed for utilizing idle slots.In the method,neighboring nodes utilized idle slots for retransmitting a packet which failed to reach the target receiver.Theoretical analysis and simulation results show that the proposed method significantly increases the probability of successful packet transmission and the network throughput.In addition,a comparison between the proposed method and IEEE 802.11p was presented via extensive simulation,and the results prove that,due to its ability to access channel determinately,the method can disseminate real-time safety information timely and stably.…”
