A new convex optimization algorithm, Primal Dual, is applied to radio interferometric imaging to recover the emission structure from the incomplete sampling. The convex optimization problem is defined as the primal problem and its dual problem is calculated. According to the characteristics of these two problems, the final solution of the primal problem is solved and the image of radio sources are reconstructed by iteratively alternating between solving the primal problem and the dual problem by using moreau decomposition, forward-backward method and the proximity operator. The algorithm parameters are analyzed from the simulations based on experimental data. The algorithm is validated and the parameters are optimized. The comparison between the images inferred from the compressed sensing and classical CLEAN algorithms shows that the signal to noise ratio and the dynamic range in the reconstructed images from compressed sensing are significantly higher than the CLEAN images, and the sidelobe levels are much lower in the former based on the real data. Besides the obvious efficacy of the Primal Dual algorithm in reconstructing extended source images, the major attraction is that it is simple to parallelize to support large data sets.","PeriodicalId":303632,"journal":{"name":"2018 13th APCA International Conference on Control and Soft Computing (CONTROLO)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123702402","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}

This circuit is based on the two stage circuits to achieve full frequency band and low power consumption. Current-reused technology is applied to improve the power gain in the whole frequency band and reduce the DC loss in the drive stage. Simultaneously., a forward-body-bias-structure is added to the substrate end of the transistor, and the low power consumption is obtained by reducing the supply voltage. The cascade structure is used to improve the level of output power in power stage. Furthermore, in order to cover the whole bandwidth of UWB system, the input matching uses the T-type impedance transformation network to realize the low quality factor. Meanwhile, the RC AC-feedback-network is employed to improve the gain flatness of whole frequency band in the input and output terminals. The simulation results shows that the power amplifier achieves the saturation output power of 8dBm., an output IdB compression point of 4.3dBm., a power gain and gain flatness of $mathbf{15}pm mathbf{1dB}$, input and output reflection coefficients of below −6.5dB and −7.6dB respectively, while only consumina 14.4mW from a 0.9V power supply with a die area of $mathbf{0.74}times mathbf{0.71 mm}^{2}$.","PeriodicalId":303632,"journal":{"name":"2018 13th APCA International Conference on Control and Soft Computing (CONTROLO)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134338637","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 entire transmission process is divided into wireless energy harvesting phase and full-duplex information transfer phase, which is termed as the time switching scheme. For wireless full-duplex relay networks, the transmit power of the source node is always same in the two phase. Therefore, the proposed joint optimal power allocation and relay selection strategy can obtain the different transmit power of the source node in two phase and then select the optimal cooperative relay from the relay set, which aims to maximize the information rate under the condition of total power limitation. Using Lagrangian multiplier method, the closed-form expressions of optimal transmit power can be obtained. In addition, two cases depending on the number of antennas used for energy harvesting are considered, which can fully exploit the hardware resources. Simulation results show that the proposed FD scheme has better performances than the existing schemes.","PeriodicalId":303632,"journal":{"name":"2018 13th APCA International Conference on Control and Soft Computing (CONTROLO)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131340755","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}
