编写语法分析程序，实现对算术表达式的语法分析。要求所分析算数表达式由如下的文法产生： E->E+T|E-T|T T->T*F|T/F|F F->id|(E)|num-Write parser to achieve parsing of arithmetic expressions. Requirements analysis arithmetic expressions generated by the following grammar: E-> E+ T | ET | T T-> T* F | T/F | F F-> id | (E) | num

This script was designed as a stand alone script which can be easily intergrate into any existing website as it is,but if you want to intergrate it into a site which uses a content management format, then some alterations will have to be done for it to work properly. Remember this is a project and I am constantly working to improve it, so I can t guarantee that it will work for everyones needs, but dammmmd close. -This script was designed as a stand alone script which can be easily intergrate into any existing website as it is, but if you want to intergrate it into a site which uses a content management format, then some alterations will have to be done forit to work properly.

学vc编游戏的配套光盘 要编译[学vc编游戏]源程序一定要运行“学vc编游戏.exe”将程序解包到硬盘上。不要直接用拷贝光盘的办法(直接拷贝的文件是只读属性的)。-the cd of if you want to compile the source file in the cd-rom,you must run "学VC编游戏.exe" to extract program onto hd.don t copy from cd directly(the attr of the directly copying file is read only)

WLAN仿真－发送机 wlan No Comments 设置完系统参数后，开始产生发送数据。 1. 产生随机的发送bit（tx_bits），这里不考虑信道编码。 2. QAM映射 3. 将数据映射到不同载波，形成OFDM符号 4. 产生pilot，并将pilot插入OFDM符号中 5. 加入dc和guard子载波 6. 进行ifft，将频域信号变到时域，并加入循环前缀 7. 对信号进行overlap window 8. 在时域产生short preamble 9. 在时域产生long preamble 10. 将preamble和数据符号组成packet 11. 升采样 得到信道传输的数据Tx_signal_up 具体程序见附件 wlan_transmitter.m-WLAN Simulation- wlan No Comments transmitter system parameters set finished, the beginning to have to send data. 1. Have sent random bit (tx_bits), here does not consider channel coding. 2. QAM mapping 3. The data is mapped to a different carrier to form OFDM symbols 4. Have a pilot, and pilot inserted OFDM symbols 5. Adding dc and guard subcarriers 6. To carry out ifft, will change the frequency domain signal to time domain, and add cyclic prefix 7. the signals overlap window8. In the time domain have a short preamble9. In the time domain have a long preamble10. the preamble and data symbols packet11. or sampling re

这是一系列实现类的方法，很好，它综合了所有的实现方法-This is the realization of a series of class methods, very good, it integrates all the way to achieve
