相干解调 [通信] coherent demodulation
- 使用正交检测法进行相干解调,并使用一种改进的数字相关器进行解扩。
It uses orthogonal detection method for coherent demodulation; and uses an improved digital correlator for de-spread. - 在数字相位调制系统的相干解调过程中,普遍存在着载波相位模糊问题。
In digital phase modulation system, there always exists carrier phase-ambiguity in the process of coherent demodulation. - 其中,载波同步是同步的一个重要分支,是实现相干解调的基础。
Carrier synchronization, as an important branch of synchronization technology, is the foundation of coherent demodulation.
