The compensator of memoryless nonlinearity is composed of a nonlinear subsystem without memory and a dynamic linear subsystem. The model parameters of Wiener model are measured by using harmonic distortion information in ADC output by sinusoidal signal stimulation. The results of experiment indicate that the spurious free dynamic range (SFDR) of this technique achieves about 20-dB improvement. Frequency sweeping results show that the parameters of nonlinear compensator can be acquired by a training signal excitation. With the help of narrowband-dithering technique, the Wiener model based compensator results in extra 10-dB improvement in SFDR by tiny cost of signal-to-noise ratio.","PeriodicalId":383024,"journal":{"name":"2014 IEEE Workshop on Electronics, Computer and Applications","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125723563","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}

As users' requirement for information sharing increases continuously, the on-demand sharing and synchronization for heterogeneous and complicated data becomes a serious issue to be solved. Firstly, the information sharing technology is researched in this paper, and a two-layer metadata standard is proposed. The first layer of metadata provides a uniform description format for one type of data, and the second layer of metadata manages the first layer of metadata to shield the difference among multi-class metadata formats. Secondly, an information sharing system is established to realize the multi-class data synchronization between different users.
