Aiming at the scheme of the signal electromagnetic environment simulator of the wireless communication system, the mission of this project is to design and realize the conversion of high speed parallel signal to serial signal and conversion of high speed digital signal to analog signal. the signal comes from the v / uhf wave band of the background simulator
本課題的任務是針對通信信號電磁環境模擬器系統的方案要求，設計實現背景信號模擬器v uhf波段後端高速信號的復接與d a轉換，為后級的頻率綜合器的信號頻譜搬移提供了基本信號。 -
I don ' t believe into any groundbreaking revolutions after epc standards were created and uhf regulations opened uhf band for rfid use
我相信沒有什麼比epc標準和為使用rfid而開放超高頻頻段，設立規則更有革命性突破意義了。 -
This method can adapt to both time and frequency domain, similarly can be used to discuss about targets upon ground or sea surface. with this method the scattering waves of a truck model are studied in uhf band
復合激勵法使用范圍廣泛，不僅適用於時域，也適用於頻域，不僅時用於地表目標的電磁散射研究，也同樣也適用於海面等環境下目標的電磁散射研究。
