Pilot

This demonstration models a flight control for the longitudinal motion of a Grumman Aerospace F-14 T

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－系統參數配置系統參數主要分為2類：一類是可以配置的

WLAN仿真－系統參數配置系統參數主要分為2類：一類是可以配置的，可以根據使用者的需求改變的參數 1）你打算讓這個仿真跑多少個OFDM符號？ 2）你打算采用什么樣的調制方式？ 3）你打算讓你的系統跑在什么樣的環境下，AWGN？Rayleigh fading? 4）你的接收端采用什么樣的配置，比如，是否采用理想均衡，線性插值均衡，理想同步，頻偏糾正等等？ 5）你的信道采樣頻率是多少？你的載波頻率是多少？一類是固定不變的，發送端按照協議規定設置的一些參數 1）子載波個數，包括數據子載波，導頻子載波。 2）保護間隔，Pilot和preamble的數值。舉例：比如將這些參數匯總在一個m文件，global_parameter.m

WLAN仿真－發送機 wlan No Comments 設置完系統參數后

WLAN仿真－發送機 wlan No Comments 設置完系統參數后，開始產生發送數據。 1. 產生隨機的發送bit（tx_bits），這里不考慮信道編碼。 2. QAM映射 3. 將數據映射到不同載波，形成OFDM符號 4. 產生Pilot，并將Pilot插入OFDM符號中 5. 加入dc和guard子載波 6. 進行ifft，將頻域信號變到時域，并加入循環前綴 7. 對信號進行overlap window 8. 在時域產生short preamble 9. 在時域產生long preamble 10. 將preamble和數據符號組成packet 11. 升采樣得到信道傳輸的數據Tx_signal_up 具體程序見附件 wlan_transmitter.m

Interference Analysis

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.
