To reduce the power consumption, the proposed voltage controlled oscillator (VCO) employs a complementarily cross-coupled architecture. Under 1.5V and 0.6V supply voltage of Mixer and VCO, respectively, the simulated results of the proposed Mixer reveal a conversion gain of 10.74dB, input third-order intercept (IIP3) of −4.8dBm, phase noise of −116.2dBc/Hz at 1 MHz offset and tuning range of 4.615GHz~5.335GHz (14.12%) while total power consumption is only 7.3mW.

When compared with direct slot capacitance, spiral capacitance can improve coupling of capacitance, thus lower resonant frequency is obtained for the same circuit size. Simulated results show that a 3.57 GHz lower resonance is achieved, which is useful for the design of miniature devices. Based on the proposed DGS and spiral split ring resonators (SSRR), a compact dual stopband filter (DBSF) is designed and fabricated in this paper.

Due to the phase error caused by target's non-cooperative motion, we can't use conventional Fourier transform in ISAR imaging reconstruction. Therefore, the method of Range Instantaneous Doppler (RID) technique based on Fractional Fourier Transform (FRFT) is presented. First, we define a model of the ISAR received signal that is valid for maneuvering targets. In order to eliminate phase error caused by translational motion components, the strong scatter signal that backscattering from the target is used for phase compensation, which can be extracted from the echoes using FRFT. Finally, RID is proposed to reconstruct ISAR image. After time-frequency transform named SPWVD, we get the instantaneous Doppler frequency. Even without exact motion compensation, a clear image of the target, such as aircraft, is obtained, which avoids the insufficiency of conventional Fourier-based image algorithm. The theoretical analysis is validated by presenting and discussing the simulation results.","PeriodicalId":211786,"journal":{"name":"2010 International Symposium on Signals, Systems and Electronics","volume":"957 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120864350","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}

There are four resonant modes inside pass-band of the novel filter, two of which are generated by dual-mode resonator and the other two modes are produced by parallel-coupled feed lines. This results in the formulation of the novel UWB filter with wide bandwidth and compact size.

In order to improve the spectrum utilization efficiency, secondary users can share the spectrum with primary users, where the primary users can get revenue due to quality of service performance (QoS) degradation and secondary users can meet their demand of the spectrum. In this paper, we establish a system model composed of multiple primary and secondary controllers in cognitive radio networks. Each controller operates at multiple frequency points and connects multiple users. The primary controllers connecting local users are spectrum sellers and buyers are secondary controllers serving secondary users. We obtain the equilibrium for spectrum trading through the demand and the supply function. Two cases are considered where controllers are aware of others. Case I is multiple equilibriums are obtained at the same time and in case II controllers not in equilibrium states for some frequency can get the pricing information of others which have realized spectrum trading. The two cases are investigated and performances are analyzed.","PeriodicalId":211786,"journal":{"name":"2010 International Symposium on Signals, Systems and Electronics","volume":"635 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128748034","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}
