This m-file displays the time waveform for the Gaussian pulse function and the first and second derivatives of the Gaussian pulse function for a 0.5 nanosecond pulse width. Other values of pulse widths may be used by changing fs,t,t1. The program uses the actual first and second derivative equations for the Gaussian pulse waveforms. The first derivative is considered to be the monocycle or monopulse as discussed in most papers. The second derivative is the waveform generated from a dipole antenna used in a UWB system. Other information is contained in the file.

Implemented BFS, DFS and A* To compile this project, use the following command: g++ -o search main.cpp Then you can run it: ./search The input is loaded from a input file in.txt Here is the format of the input file: The first line of the input file shoud contain two chars indicate the source and destination city for breadth first and depth first algorithm. The second line of input file shoud be an integer m indicate the number of connections for the map. Following m lines describe the map, each line represents to one connection in this form: dist city1 city2, which means there is a connection between city1 and city2 with the distance dist. The following input are for A* The following line contains two chars indicate the source and destination city for A* algorithm. Then there is an integer h indicate the number of heuristic. The following h lines is in the form: city dist which means the straight-line distance from the city to B is dist.

This m file analyzes a coherent binary phase shift keyed(BPSK) and a amplitude shift keyed(ASK) communication system. The receiver uses a correlator(mixer-integrator[LPF]) configuration with BER measurements comparing measured and theoretical results. The bandpass and low pass used in the receiver are constructed using z transforms.

本文件描述了一个基于串口实现文件传输的协议eXmodem，该协议基于标准Xmodem File Transfer Protocol，是一个独立标准，完全功能，全新的文件传输协议。 1)该协议除实现Xmodem File Transfer基本功能，即已实现了在两个设备相互之间，通过串口把一个设备内文件传输至另一个设备内；其增强功能所列参考如下： a)两个设备相互之间传输文件能够以一致的文件目录存放； b)两个设备相互之间可以传输任意大小的文件，而Xmodem File Transfer只能传送128 *n字节大小的文件； c)具备避免一个文件在两个设备相互之间重复传输的功能，提高了文件传输的效率。
