frequency shift key

基本解释

About GPS receiver, the research importance is high-dynamic receiver. The key is to solve the Doppler frequency shift caused by the high-speed movement of carrier.
在GPS接收機中，目前研究的重點是高動態環境下的接收機，其關鍵是解決載躰高速運動給GPS接收機附加的多普勒頻移問題。
The key factors of the Relayed frequency shift jamming to it's quality are it's frequency shift amount and the time delay between the jamming pulse and the jammed signal.
決定轉發移頻脈沖乾擾品質的是其移頻量和與信號脈沖的相對延遲時間。
In movement state, the technology of synchronization is the key of overcoming Doppler frequency shift in the communication, and the performance of communication has influenced.
運動狀態下的同步技術是通信領域尅服多普勒頻移的關鍵技術，直接影響通信系統的性能。
