This demonstration models a flight control for the longitudinal motion of a Grumman Aerospace F-14 Tomcat. First order linear approximations of the aircraft and actuator behavior are connected to an analog flight control design that uses the Pilot s stick pitch command as the set point for the aircraft s pitch attitude and uses aircraft pitch angle and pitch rate to determine commands. A simplified Dryden wind gust model is incorporated to perturb the system.

If you have programming experience and a familiarity with C--the dominant language in embedded systems--Programming Embedded Systems, Second Edition is exactly what you need to get started with embedded software. This software is ubiquitous, hidden away inside our watches, DVD players, mobile phones, anti-lock brakes, and even a few toasters. The military uses embedded software to guide missiles, detect enemy aircraft, and Pilot UAVs. Communication satellites, deep-space probes, and many medical instruments would have been nearly impossible to create without embedded software.

WLAN仿真－系统参数配置 系统参数主要分为2类： 一类是可以配置的，可以根据使用者的需求改变的参数 1）你打算让这个仿真跑多少个OFDM符号？ 2）你打算采用什么样的调制方式？ 3）你打算让你的系统跑在什么样的环境下，AWGN？Rayleigh fading? 4）你的接收端采用什么样的配置，比如，是否采用理想均衡，线性插值均衡，理想同步，频偏纠正等等？ 5）你的信道采样频率是多少？你的载波频率是多少？ 一类是固定不变的，发送端按照协议规定设置的一些参数 1）子载波个数，包括数据子载波，导频子载波。 2）保护间隔，Pilot和preamble的数值。 举例：比如将这些参数汇总在一个m文件，global_parameter.m

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

We were on the lookout for ice. I was in a 32 foot sailing yacht with writer and explorer Tristan Gooley, undertaking a double-handed sail from Scotland through the Faroes up to 66 33 45.7 N and the midnight sun. Now sailing out of the Arctic Circle we were approaching Iceland from the north, heading for the Denmark Straits, where ice flowed south. The Admiralty Pilot warned of bergs but the ice charts we had sailed with were over a week old. We needed an update.
