In which the sensors is less then the signals to be separated. As LFM signal belongs to nonstationary signal, the proposed method is based on Time Frequency Distribution (TFD) analysis. Through suppressing the cross term of the TFD, auto term become prominent. A rotation way utilizing the auto term points is presented, by which the TFD area of each LFM signal is classified. Using the STFD matrices corresponding to the auto term points, the Direction Of Arrival (DOA) of each LFM signal can be estimated individually. Through simulation, it is proved that the proposed method is effective.","PeriodicalId":394548,"journal":{"name":"2012 Second International Conference on Instrumentation, Measurement, Computer, Communication and Control","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133442386","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}

Otherwise, micro-scanning can make up for the drawback that the low detected accuracy cannot be satisfied to the requirement of a high accuracy detection due to the less detector pixel number in measurement of optical system. In this paper, a new standpoint of combining HWS with micro-scanning technique has been put forward, and then HWS realizes a high detected accuracy with low detector pixel number. It mainly discusses the system structural form of the new Hartmann wave front sensor, the selection of added micro-scanning mode and the related analysis of precision.","PeriodicalId":394548,"journal":{"name":"2012 Second International Conference on Instrumentation, Measurement, Computer, Communication and Control","volume":"42 10","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131776984","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 background, key issues and research solutions about triggering of convergence services are introduced. To achieve services triggering, the anchor control platform with call redirection and signing control function between CS and IMS is designed. After analyzing the process that anchor mechanism completes services triggering and offers consistent services regardless of accessing from CS or IMS, the paper evaluates the effects in real-application domains. Thus anchor mechanism is demonstrated to be an ideal solution for the coexistence period of CS domain and IMS domain, exhibiting practical feasibility and application value.","PeriodicalId":394548,"journal":{"name":"2012 Second International Conference on Instrumentation, Measurement, Computer, Communication and Control","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131989707","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}

At the same time, it also can worsen the bit error ratio performance in multi-carrier system. In this paper, a nonlinear LDPC-OFDM system has been the research background for reducing the high clipping noise and distortion in clipping system. A novel algorithm named minimum mean square error (MMSE) iterative reception algorithm has been proposed in this paper, which is based on Ochiai clipping distortion mitigating algorithm and clipping distortion reconstructing iteration (CDRI) method. The MMSE iterative reception algorithm combined MMSE algorithm with iterative reception method to reduce clipping noise and distortion under various iteration times. At the same time, LLR-BP process has been intruded to decode LDPC and optimize BER performance. On the other hand, clipping process in LDPC-OFDM system has been mapped to a series of clipping index coding, and maximum likelihood (ML) decision algorithm has been used to recognize them.","PeriodicalId":394548,"journal":{"name":"2012 Second International Conference on Instrumentation, Measurement, Computer, Communication and Control","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133157483","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}
