Ternary complementary sets and its application in UWB by WANG Shi-ji, ZHANG Nai-tong

“…Ternary complementary set based UWB signaling employing a set of orthogonal chip pulses was proposed for DS-UWB.It had many advantages in indoor high-speed short range communications.First the system model of multiple access communications was founded,then ternary complementary set and its recursive construction method were analyzed,and then the performance evaluation structure of multiple access communications based the ternary complementary sets by use of the Rake receiver was put forward.Ternary complementary sets assigned to two users had good aperiodic autocorrelation functions.Hence,the multipath interference as well as multiple access interference were mitigated.Simulation results show that ternary MO complementary sets have better performances compared with other random sequences in the SV/IEEE 802.15.3a channel model.…”

Pilot Position Optimization Design of WLAN System Based on Experiment by Jue Lan, Yunzhou Li, Xin Su, Shidong Zhou

“…Considering the frame structure of IEEE 802.11ac with “leading preamble plus comb-like pilot”，the performance evaluation formula of the correction scheme based on maximum likelihood estimation was derived，according to which the effect of pilot location，channel fading and subcarrier correlation was studied.Furthermore，a signalling exchange method was proposed，which ensured pilot position synchronization on both end，and a low complexity algorithm of pilot optimization according to the frequency channel amplitude information.In this way，the pilot overhead can be reduced without loss of correction performance.The experiment and simulation result shows that for ideal Rayleigh channel data，correction performance improves by 1.85 dB and 7.15 dB for unknown channel amplitude information in frequency domain and known cases respectively.For field experiment channel data，correction performance improves by 1.67 dB and 2.68 dB respectively.…”

Symbol timing recovery algorithm based on ordered statistic of maximum mean power timing for WBAN by HIYu C, HENLan C, VChao L

“…The symbol timing algorithm based on maximum mean power timing is independent of carrier phase offset,and has the property of capturing timing information fast,which meets the demand of wireless body area networks (WBAN).According to IEEE 802.15.6 standard,the ordered statistic of maximum mean power timing was used to reduce the computational complexity in the symbol timing process.The theoretical analysis and simulation results shows that the proposed algorithm can achieve symbol timing within 32 symbols and reduce the computational complexity by ninety percent at most compared to the original maximum mean power algorithm.The fast synchronization and car-rier-independence property of the proposed algorithm can also make room for carrier-offset recovery and frame synchro-nization.…”

Research on accurate ranging of UWB under indoor environments by WU Shao-hua, ZHANG Nai-tong

“…The accurate ranging ability of ultra wideband（UWB） signal under IEEE 802.15.4a indoor channel model was studied.An improved time-of-arrival（TOA） estimation algorithm which utilizes region search and threshold comparison was proposed.By statistical analysis on certain characteristics of the CM1 and CM2 channel profiles,the probability model of TOA estimation error was deduced.The thresholds of the proposed TOA estimation algorithm were then set by limiting the error probability to the lowest level.The mean absolute ranging errors under different SNR were simulated.Results show that high enough SNR should be guaranteed in order to obtain centimeter-level ranging precision under in-door environments,while extremely high SNR would not help to improve the ranging precision any more but lead to a performance floor.The results have instructional significance on designing localization algorithms and transmission power control in practical ranging.…”

“…Dispersion of the signal energy and the inter symbol interference（ISI）is caused by the multipath fading in 60GHz pulse communication environment.To solve this problem,the severity of the ISI in the system was analyzed,and the method to eliminate interference was studied.Based on the 60GHz wireless channel model established by IEEE 802.15.3c,the simulation platform of 60GHz pulse communication system was built.Theoretical analysis and numerical simulation of ISI in the system were carried out,and a receiver scheme of combining Rake receiver and equalizer was designed.Results show that,the two taps MRC-Rake receiver module combined with MMSE linear equalization module can not only improve the signal energy by multipath diversity,but also eliminate ISI.The performance of the system was improved without increasing the complexity.The scheme provides a reference for the design of 60GHz pulse communication system in the future.…”

Detection of sybil attacks based on periodic ultra wide band distance information in WSN by Yanzhi ZHANG, Xiaoqin YE

“…Concerning the problem that wireless sensor network is vulnerable to many kinds of network attacks and compromise of nodes，a complete detecting system of sybil attack based on periodic ultra-bandwidth distance information was proposed.Firstly，the distance between the adjacent nodes was ranging and the hello data packet was exchanged.Then，the distance estimation form was constructed by local estimation，and the form was contained in each node.Meanwhile，multiple distance matching check was periodically executed for each node in the network.Finally，when there was the distance matching between the legitimate node at least two different nodes，it would give an alarm and discard the sybil nodes.If there was no distance matching，the node continued normal operations.IEEE 802.15.4 peer to peer sensor networks were adopted in the simulation experiments.Experimental results show that the proposed system not only can tolerate changes in the number of complicated sybil attacks，but also can successfully deal with the occurrence of complicated，malleable sybil attack.In addition，the probability of false alarm is very small，the entire network performance and its consistency are not affected.…”
