无载波 meaning in Chinese

carrier-free

Cap carrierless amplitude modulation
无载波幅度调制
An atm term . carrierless amplitude / phase modulation with 64 constellation points
异步传输模式术语。采用64点星座图的无载波调幅调相码。
No carrier usually indicates that the receiver has hung up and the carrier has been dropped
无载波通常表明接收方已挂断且载波已被丢弃。
Carrierless amplitude and phase modulation has emerged as the de facto standard , having captured most of the nascent market to date
无载波振幅和相位调制正在成为事实上的标准，迄今已占了这个新生市场的大部分。
Furthermore , it is insure that the carrier pahse measurement data does not have cycle slips in gps based attitude determination system , using phase rate prediction algorithm and baseline length constraint information algorithm , the cycle slips can be detected and corrected successfully , which markedly reduce the initialization numbers of attitude determination system
此外，在gps姿态测量系统中，必须保证载波相位观测数据中无载波相位周跳，本文提出的多普勒预测算法和基线长度约束相结合的方法能有效的检测和修正载波相位整周模糊值固定前和固定后的周跳问题，减少了姿态测量系统重新初始化的次数。
