This a very simple baseband simulator for SC-FDMA system. This simulator is part of the upcoming book “Single Carrier FDMA: A New Air Interface for Long Term Evolution” (Wiley, Nov. 2008) which I co-authored with professor David J. Goodman at Polytechnic University. The purpose of this simulator is to give some concrete idea of how SC-FDMA system works. It does lack many realistic and sophisticated features such as channel coding, time-varying fading channel model, soft decision decoding, etc. Regardless, I am hoping that it will help you understand SC-FDMA which is a fairly new development in 3GPP LTE.

是一本介紹java基礎應用的好書 Java For Artists targets both the undergraduate computer science or information technology student and the practicing programmer. It is both an introductory-level textbook and trade book. As a textbook it employs learning objectives, skill-building exercises, suggested projects, and self-test questions to reinforce the learning experience. The projects offered range from the easy to the extremely challenging. It covers all the topics you’d expect to find in an introductory Java programming textbook and then some. As a trade book it goes purposefully deeper into topics cut short or avoided completely in most introductory textbooks. Its coverage of advanced GUI programming techniques, network programming and object-oriented theory will enable you to take your skills to a higher level.

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

The smspdulib library is intended for more transparent interaction with SMS PDU. This thought over hierarchy of classes will allow you to create new classes for other types of short messages using the realized base functionality. At present, the following types of short messages are supported: status report, SMS (with long (large) SMS parts support)
