Finally, emulated studies are made on effects of CE for wideband BJ and comb BJ with different threat level on different FH rate and different FH bandwidth.

In this model, original complex spectral occupancy phenomenon is decomposed into several simpler components among which relatively stable Intrinsic Mode Functions (IMFs) are predicted by AR model and the residue with tendency is modelled by Volterra series expansion; both of AR and Volterra's coefficients are modified by RLS algorithm in a centralized way. We compared the model with stand-alone use of AR model and Volterra adaptive filters for one-step prediction and employed RMSE for performance comparison. The results have demonstrated that the hybrid model enhances the accuracy of prediction to behaviors of spectrum driven from nonlinear and non-stationary processes.","PeriodicalId":224387,"journal":{"name":"2016 IEEE International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"23 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":"126353020","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}

Lossless foam is used as the medium while the absorbing band is promised. Lumped resistors are chosen to absorb microwave other than ink that can reduce the complexity of process. After simulating by CST Microwave Studio 2012, the result shows that from 13.5 GHz to 17.5GHz, reflection coefficient is lower than −10dB.

In this paper, a method based on 2-D data of inverse synthetic aperture radar (ISAR) images is proposed.

The growing requirement of a new generation of wireless communication system for high-speed data communication and bandwidth makes the scarcity of spectrum resources an inevitable problem. With new spectrum methods and strategies coming out, more efforts have been made to this field. This article compares and analyzes recent different dynamic spectrum access methods, on basis of which we propose a modified spectrum access method to enhance spectrum efficiency. Meanwhile simulation and analysis of this method is presented at the end of this article. A new feasible spectrum access algorithm is proposed using hill climbing approach to computes the parameters of spectrum access. Then collaborative access and non-collaborative spectrum access are different in estimating the interference temperature to the primary receivers. Afterwards simulation and comparison of collaborative approach are presented as well.","PeriodicalId":224387,"journal":{"name":"2016 IEEE International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"33 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":"132113293","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}
