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

猜猜我是谁游戏源码。照片图像逐步细化显示，在聚会时做游戏用-Guess Who game source. Photos gradually thinning, the gatherings do with the game

源代码是关于游戏的，利用面向对象编程技术，抽象出各种类，例如子弹，敌机，我方的飞机。还有世界类。 然后利用动态绑定的原理，实现虚函数。利用链表类实现多线程。而且是游戏核心代码，没有添加任何商业性的东西，代码可移植性好。不受制于操作系统以及编译器的制约。对于想要学习游戏编程的新手来说非常适于学习。代码注释详细，逻辑清晰。各种碰撞检测，以及NEW的技术。
