Analysis of super-long and sparse feature in pseudo-random sequence based on similarity by Chun-jie CAO, Jing-zhang SUN, Zhi-qiang ZHANG, Long-juan WANG, Meng-xing HUANG

“…Similarity analysis of pseudo-random sequence in wireless communication networks is a research hotspot problem in the domain of information warfare.Based on the difficulties in super-long sequence,extremely sparse feature,and futilities in engineering application for real-time processing exist in similarity analysis of sequence in wireless net-work,a method of similarity analysis of sequence in a certain margin of misacceptance probability was proposed.Firstly,the similarity probability distribution of real-random sequence was theoretically analyzed.Secondly,according to the standard of NIST SP 800-22,the randomness of pseudo-bitstream was analyzed and the validity of pseudo-bitstream was judged.Finally,similarity was analyzed and verified by combining super-long pseudo-random sequence in real wireless communication networks.The results indicate that the lower bound of similarity value is 0.62 when misacceptance prob-ability uncertainty at about 1%.Above conclusion is considerable importance from the significance and theoretical values in network security domains,such as protocol analysis,traffic analysis,intrusion detection and others.…”

A Multi-User Subcarrier Power Joint Allocation Algorithm Based on Rate Fairness by Jianwu Zhang, Lu Jin, Xiaorong Xu

“…With the rapid development of wireless communication technology，the demand for wireless resources increases quickly，and to improve the quality of service are required by users.Therefore，the intelligence is needed to carry out an effective compromise between user quality of service（QoS）requirements and wireless resource constraints in future communication systems.In order to enhance the spectral efficiency in cognitive radio network（CRN），multi-user subcarrier power joint allocation algorithm based on rate adaptive（RA）criterion in cognitive orthogonal frequency division multiplexing（OFDM）system was proposed in the constraint conditions of available subcarrier，secondary user（SU）power budget and rate fairness，with the consideration of rate fairness between SUs.This algorithm was separated into two steps with subcarrier and power allocation respectively.The proposed scheme could maximize link capacity with the consideration of the fairness among all SUs.Simulation results show that the joint allocation algorithm can get effective tradeoff between system throughput and the rate fairness of SU.…”

Research on performances of single sideband modulated OFDM signals in ROF optical transmission system by LEI Xiao-yan1, CHEN Lin1, DONG Ze1, CAO Zi-zheng1, LU Jia1, YU Jian-jun1

“…A novel OFDM-ROF system using single sideband modulation technology in radio-over-fiber system to generate optical wave was proposed and experimentally demonstrated.The 2Gbit/s OFDM signal and a 10GHz RF clock were mixed.The mixed signals were applied to drive a double-arm intensity modulator to generate a single sideband signal which transmitted to base station（BS） over fiber and broadcasted by antenna after the optical OFDM signal was converted into electrical OFDM signal.The experiment results show that in 10GHz-ROF system,a 2Gbit/s OFDM signal transmitted over 200km SMF without wireless broadcasting only has 1dB power penalty.After being only transmitted over 8m wireless air distance it has 0.3dB power penalty.When the signal transmitted over both 200km SMF and wireless air distance of 8m,also can obtain a clear received constellation in the experiment.…”
