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.

小波神经网络好文章！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.

中国移动公布MMS已经有一段时间了。但是MMS的通讯开发工具并不是很多，主要是Nokia提供的工具。另外华为也提供了MMSC API，但是对于很多没有机会直接接入MMSC的开发人员来说，也无法了解更多。 北京易科思达科技有限公司推出的第一款MMS模拟器基本上解决了这个问题。它可以兼容华为的MMSC API和Nokia EAIF MMSC模拟器。它支持MMS的封包和解包。在模拟的过程当中可以通过华为的API发一个数据给模拟器，它会解开所接收到的数据包，并把相关内容打印在屏幕上，同时再重新加上封装，利用mo模式反调用API的接收接口。这样利用该模拟器就可以完成一个自测试循环。 对该模拟器感兴趣的同志，可以去下载中心里面下载多功能模拟器以及MMS的相关配置文件。在下载中心中还有一个有关MMS的解码器，以及若干用于研究的MMS例子。 MMS的封装过程十分复杂，可以说其难度是远超过短信息协议。其复杂的封装过程主要是为了兼容原有HTTP协议的同时，并减少对通信通道的数据容量压力
