frequency up conversion

基本解释

The research of frequency up conversion has been developed greatly in recent ten years.
频率上转换研究在近十年有了突飞猛进的发展，它有着非常好的应用前景。
It is concluded that the frequency up-conversion process can be used as a reliable interface for entanglement transfer.
研究表明：和频过程能够传递纠缠特性，和频前后纠缠光子的时间关联和空间关联具有很好的传递特性。
Using pseudo random code to modulate the signal's phase equals to frequency up-conversion of the pseudo random code by the carrier frequency.
信号采用伪随机编码进行相位调制，相当于是用载频对伪随机码进行上变频。
