We address the problem of blind carrier frequency-offset (CFO) estimation in quadrature amplitude modulation, phase-shift keying, and pulse amplitude modulation communications systems.We study the performance of a standard CFO estimate, which consists of first raising the received signal to the Mth power, where M is an integer depending on the type and size of the symbol constellation, and then applying the nonlinear least squares (NLLS) estimation approach. At low signal-to noise ratio (SNR), the NLLS method fails to provide an accurate CFO estimate because of the presence of outliers. In this letter, we derive an approximate closed-form expression for the outlier probability. This enables us to predict the mean-square error (MSE) on CFO estimation for all SNR values. For a given SNR, the new results also give insight into the minimum number of samples required in the CFO estimation procedure, in order to ensure that the MSE on estimation is not significantly affected by the outliers.

小波神經(jīng)網(wǎng)絡(luò)好文章！A method for fault detection is proposed using a trained neural network as the nominal model of the system to be monitored. Partial physical knowledge, if available, can be combined with the nominal model to perform fault isolation.

After an introduction to the history of mobile communications, this guide considers the basics of mobile radio, the design of cellular and private radio systems, and issues of interworking with the fixed network. It then looks at the role of the mobile radio operator, the design and operation of mobile radio networks, the needs of large user groups, and relevant regulatory and government decisions. A final section focuses on career development through resolution of conflicts, understanding managerial issues, and professional vehicles.

中國移動公布MMS已經(jīng)有一段時間了。但是MMS的通訊開發(fā)工具并不是很多，主要是Nokia提供的工具。另外華為也提供了MMSC API，但是對于很多沒有機會直接接入MMSC的開發(fā)人員來說，也無法了解更多。 北京易科思達科技有限公司推出的第一款MMS模擬器基本上解決了這個問題。它可以兼容華為的MMSC API和Nokia EAIF MMSC模擬器。它支持MMS的封包和解包。在模擬的過程當(dāng)中可以通過華為的API發(fā)一個數(shù)據(jù)給模擬器，它會解開所接收到的數(shù)據(jù)包，并把相關(guān)內(nèi)容打印在屏幕上，同時再重新加上封裝，利用mo模式反調(diào)用API的接收接口。這樣利用該模擬器就可以完成一個自測試循環(huán)。 對該模擬器感興趣的同志，可以去下載中心里面下載多功能模擬器以及MMS的相關(guān)配置文件。在下載中心中還有一個有關(guān)MMS的解碼器，以及若干用于研究的MMS例子。 MMS的封裝過程十分復(fù)雜，可以說其難度是遠超過短信息協(xié)議。其復(fù)雜的封裝過程主要是為了兼容原有HTTP協(xié)議的同時，并減少對通信通道的數(shù)據(jù)容量壓力
