With the increasing variety of telecommunication business and needs for more and more client connections, the application servers are faced with the challenge of the overload of tremendous requests. On the Windows platform, components programming provides distribution structure at the business level. And at the user level, I/O completion port is a best way for the scalability. In this paper, we describe the way to use IOCP.
在电子监测系统中,调制类型的自动识别起着非常关键的作用。当调制类型较多时,一些识别算法第一步先区分调制方式是属于模拟调制还是数字调制。该文采用了结合小波变换的VSSR(Variance of Subclass’s Symbol Rate)法,仿真表明,当源信号的任何情况都未知下,在采样点较多时,可以在信噪比仅为10dB的情况下,区分出几乎所有的数字调制和模拟调制。
