In the testing system, rotary table was used to provide standard rate, FOG was testing criteria, and MEMS gyro was tested gyro. Butterworth low-pass filter combined with moving-average filter was also designed to smooth the output of these gyros. Testing and computing methods of main technical parameters such as scale factor, nonlinearity, max input rate, etc were analyzed and system modeling of gyro was carried out by identification method to enhance the accuracy of data acquisition. Within GSM mobile communication network, GPRS wireless terminal was used to acquire data of gyro testing remotely via Internet. Moreover, Virtual instrument techniques were used to testing functions such as data acquisition & processing of two gyros, data & waveform display, data printing & storage, etc. Besides, a buttery power supply system was designed. Experiment result shows that the testing system is able to acquire data remotely and tested parameters & gyro model can represent the actual state of tested gyro. Its accuracy & real-time performance as well as the power super subsystem meet the design requirements.","PeriodicalId":360796,"journal":{"name":"2013 Third International Conference on Instrumentation, Measurement, Computer, Communication and Control","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133952590","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}

We use the Unique Word (UW) to be the cyclic prefix and the pilot just like IEEE802.16. The UW is not need to delete in receiver, so the overhead of system is low. The 2D-MMSE estimation is simplified as an MMSE interpolation in the frequency domain cascaded by an MMSE filter in the time domain. The SVD method is adopt to reduce the complexity and keep the estimation accuracy. We also make the noise variance estimation by UW. Finally, the simulation results show that the proposed algorithm has better performance than the LS and MMSE algorithms, and the complexity of our method is lower than traditional one-dimensional MMSE.","PeriodicalId":360796,"journal":{"name":"2013 Third International Conference on Instrumentation, Measurement, Computer, Communication and Control","volume":"146 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130293656","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 includes green AP clustering where Fuzzy K-mean algorithm is used, AP's second selection which is aimed to use fewer APs to guarantee the whole coverage, and AP's transmitting power optimization which aims to save more energy and reduce frequency interference better.
