spread spectrum communication

基本解释

The availability of low orbit satellite spread-spectrum communications is impacted by the complicated radio environment in China and Southeast Asia.
由於中國國內和東南亞地區電磁環境複襍，影響了低軌衛星擴頻通信的可用性。
With its spread-spectrum technology to perfect the theory and technology, spread-spectrum technology and mobile communications will be more closely linked.
隨著擴頻技術自身理論和技術趨於完善，擴頻技術與移動通信的聯系也將越來越緊密。
Frequency hopping is a spread-spectrum communications technique, meaning that the total available spectrum is split up into smaller sections so as to be better utilised.
頻跳是傳播光譜通信技術，意思被分離入更小的部分以便更好運用縂可利用的光譜。
