This m-file simulates MPSK (theoretical and simulated) with Gray coding This m-file simulates MPSK (BPSK,QPSK,8PSK)with theoretical and simulated results using Gray coding. Numerical examples of a satellite link design are shown using QPSK and/or 8PSK when the bit rate(Rb)is greater than the channel bandwidth Wc (Band-limited channel).

1.left.aspx下部分实现了读取RDF(RDF format feeds,是描述web资源的W3C XML格式)格式的feeds,可点击第三条“RDF Test”进行对比。 RDF与普通XML的主要区别是它的根节点下是<items>,而不是<channel>。 2.运行时,需要根据自己的机子改变RssReader.cs中的 String connStr = @"Data Source=6998D47256954C1\SQLEXPRESS Initial Catalog=rss Integrated Security=True"

A one-dimensional calibration object consists of three or more collinear points with known relative positions. It is generally believed that a camera can be calibrated only when a 1D calibration object is in planar motion or rotates around a ¯ xed point. In this paper, it is proved that when a multi-camera is observing a 1D object undergoing general rigid motions synchronously, the camera set can be linearly calibrated. A linear algorithm for the camera set calibration is proposed,and then the linear estimation is further re¯ ned using the maximum likelihood criteria. The simulated and real image experiments show that the proposed algorithm is valid and robust.

An AHB system is made of masters slaves and interconnections. A general approach to include all possible "muxed" implementation of multi layered AHB systems and arbitrated AHB ones can be thought as an acyclic graph where every source node is a master, every destination node is a slave and every internal node is an arbiter there must be one and only one arc exiting a master and one or more entering a slave (single slave verus multi-slave or arbitrated slave) an arbiter can have as many input and output connections as needed. A bridge is a special node that collapses one or more slave nodes and a master node in a new "complex" node.

MPEG TS Utils application provides the user with a visual representation of the multiplexed stream structure of MPEG-2 Transport Streams (ISO/IEC 13818-1). The application allows the user to investigate the basic transport stream packets with their fields. The application also allows the user to manipulate with transport streams by filtering specified PIDs and exporting to file, demultiplexing to PES and ES streams, converting multi-program TS to single-program TS.
