The bit error rate (BER) performance of MIMO system under multipath channel will deteriorate seriously, and the merit of spread spectrum technique is its potential to reduce interference, so we proposed the method that combines spread spectrum communication technique with MIMO system to obtain a better BER performance. Extensive simulations have been conducted and we designed the MIMO system based on conventional pseudo-random (PN) sequence and complete complementary sequence (CC-S), respectively. The results of simulations illustrate obviously that utilizing spread spectrum method as an enhancement technique to eliminate multipath fading interference in MIMO system is a feasible and an effective implementation way.","PeriodicalId":224387,"journal":{"name":"2016 IEEE International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128579547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The combination of GFDM and time-reversal space-time coding (TR-STC) can improve the bit error rate (BER) performance. In this paper, we employ Walsh-Hadamard Transform (WHT) in TR-STC-GFDM systems to further enhance the system performance over frequency-selective time-variant channels. Simulation results show that with slight increase in complexity, WHT can substantially reduce the BER of the STC-GFDM systems. Meanwhile, the peak-to-average power ratio (PAPR) of the system is also reduced.","PeriodicalId":224387,"journal":{"name":"2016 IEEE International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126684538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These factors seriously affect the quality of communication and the system spectrum efficiency. In this paper, we describe the transmission characteristics of satellite communication channel and a simplified fading channel model is analyzed. Besides, several common models are taken into consideration. This model is built on C. Loo model and Corazza model to describe received signals, multipath fading and shadowing effect. Simulation results suggest that this model switches between a perfect channel state and an imperfect channel state dynamically. The research provides an important meaning for the implementation of the actual channel simulation and can be widely used in the study of satellite communication system.","PeriodicalId":224387,"journal":{"name":"2016 IEEE International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114166299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The spectrum watermark identifying the radio equipment is firstly modulated by the spread spectrum code whose code rate is very high and code length is very long in the transmitting terminal. Then it is periodically embedded in communication signals based on the additive rule. This method firstly detects whether the spectrum watermark exists, and divides the intermediate frequency communication signals into N segments in the receiving terminal. Then the spectrum watermark can be obtained by fusion decision based on the demodulation of these segmented signals. Theory analysis and simulation results show that the proposed method can effectively extract the spectrum watermark without harmful interference to normally demodulating of communication signals, and there is no need to demodulate the communication signal. The proposed method can effectively reduce the complexity of spectrum watermark extracting which provides a technique support for effectively identifying and ascertaining the radio equipment.","PeriodicalId":224387,"journal":{"name":"2016 IEEE International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"127 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116204992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the phase gradient metasurface (PGM), we firstly presented a polarization-converting metasurface reflector for circularly polarized waves. On the basis of the reflector, two reflective vortex plates were designed. Under normal incidence, high-efficiency vortex waves are obtained by illuminating one vortex plate. Under oblique incidence, high-efficiency anomalous reflection of votex waves occurs for circularly polarized waves with 0° reflection angle by illuminating the other votex plate. The results of experiment and simulation are both accordant with theoretical prediction, which convincingly verifies the high-efficiency anomalous reflection of votex waves of CP waves. This technology makes a remarkable progress which is beneficial to put metasurface into practical application.","PeriodicalId":224387,"journal":{"name":"2016 IEEE International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115222341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The type I structure consists of an “I” shaped of cut-wire pair (CWP) and a split ring resonator (SRR). In this study, we found EIT effect in metamaterial originates from magnetic interactions between resonators. Specially, by controlling the separation distance between resonators, we can obtain the destructive and constructive interferences, and thus observe the transition between EIT and EIA. The type II structure is composed of mutually perpendicular cut wire pair. This structure can efficiently control the EM wave's polarization based on high transparency and intense dispersion characteristics induced by EIT effects. Specially, its thickness is very thin and its value is about 0.017λ. Microwave experiments were also carried out to confirm our views.","PeriodicalId":224387,"journal":{"name":"2016 IEEE International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"564 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116652753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By using the S-parameter retrieval technique, the bloch impedance of the SSPP unit cell is extracted and tuned around 50 ohm in a wide frequency band to achieve good impedance matching. Then, the momentum can be matched with fewer gradient matching grooves leading to smaller size. For demonstration, a planar plasmonic waveguide based on the proposed transition structure is designed and simulated. The excellent simulation results validate high-efficiency excitation and propagation of SSPPs in broadband. The proposed plasmonic waveguide can find potential applications in plasmonic devices and integrated circuits in microwave and terahertz frequencies.","PeriodicalId":224387,"journal":{"name":"2016 IEEE International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"184 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122420850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
