For ease of supplying ac voltages, the proposed filter is achieved by particular configuration schemes with low cost inverted-microstrip structure. Two open-circuited stubs are placed inside a meander loop resonator so as to form quarter wavelength resonators, which is good to keep the compact configuration. By taking advantage of the property of LC, central frequency tunability is induced by applying low ac voltages. In the LC default state, the proposed filter has three-pole, it operates at 4.7GHz with about 41% fractional bandwidth (1.94GHz).","PeriodicalId":319991,"journal":{"name":"2015 IEEE International Conference on Communication Problem-Solving (ICCP)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127187110","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}

It employs a composite approach based on the well-known cell averaging CFAR (CA-CFAR) and ordered statistic CFAR (OS-CFAR) processors. In this case, any masking effects in multi-target situations can be avoided without increasing the computation complexity. Besides, utilization of binary integration results in a higher detection performance.

This paper proposes a sine wave parameter estimation method of local refinement search in frequency domain. It can estimate the frequency of narrowband radio frequency interference(RFI) by using fast Fourier transform(FFT) and chirp transform algorithm (CTA). Simulation shows that this method can estimate the phase of narrowband radio frequency interference accurately under the condition of low signal-to-noise ratio (SNR), and the estimating efficiency is much higher than classical algorithms.","PeriodicalId":319991,"journal":{"name":"2015 IEEE International Conference on Communication Problem-Solving (ICCP)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122968166","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}

A larger PAPR has to require a wider linear range of power amplifier (PA) in system transmitter, which will greatly decrease the efficiency of PA. In this paper, we introduce a broadband OFDM communication system which is designed and implemented on the basis of digital intermediate frequency (IF) architecture and 1×4 multiple-input multiple-output (MIMO) technology. The parameters and structure of the 1×4 MIMO-OFDM communication system are provided, and its frequency spectrum and time signal are respectively tested.

Instructed by the research on the shorting probe, the bandwidth enhancement of the proposed antenna is achieved. In order to obtain the best circularly polarized(CP) radiation performance, several types of perturbations on the shorting probe are studied and a novel perturbation structure, unequal length cross-shape shorting strips, is proposed. The simulated and measured results show that the 3dB axial ratio(AR) bandwidth of 1.6%(20MHz) is realized, which means that the proposed antenna can be used for the applications of BD3 band(1.268GHz ± 10MHz) of Beidou (COMPASS) Navigation System.","PeriodicalId":319991,"journal":{"name":"2015 IEEE International Conference on Communication Problem-Solving (ICCP)","volume":"344 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116128099","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}
