differential coherent detection
differential coherent detection 双语例句
The DPSK modem used the differential coherent detection to complete data demodulation, while, the QPSK modem used quadrature coherent demodulation based on carrier synchronization.
其中，DPSK系统采用差分相干解调的方式完成数据解调，而QPSK系统则采用相干解调方案，其难点在于载波同步的实现。
Multiple-symbol differential detection (MSDD) can narrow the performance gaps between differential detection and coherent detection.
采用多符号差分检测（MSDD）能够缩小差分检测与相干检测之间的性能差距。
We present here a novel approach for phase estimation. Through coherent detection of phase modulated signals with few reference symbols (with and without differential encoding), the approach may improve power efficiency and implement phase estimation in the same coding block.
本文提出一种新的相位估计算法，该算法利用小数据量的参考信号对相位调制信号的相干检测来提高功率效率，而且在同一编码块（同一跳）中实现相位估计。
