coherent demodulation meaning in English
相干解调
Examples
- Non - coherent demodulation of bpsk signal based on time measuring
信号非相干解调方法 - The coherent demodulation and adaptive demodulation are both realized in these forementioned systems in system view , and the corresponding theory is proved by analyzing and comparing in simulation
在systemview中仿真实现了上述信号的相干解调和自适应解调两种方法,并模拟通信的实际环境分析对比解调性能,验证前述的理论分析。 - However , the high demand in frequency domain involves precise synchronization both in time and frequency domain . while because of the different channel characteristics in each channel , the receiver needs some mechanisms to characterize the channel effects in coherent demodulation
然而，频域的高要求对应于同步技术的高要求；另外，各个子信道不同的信道特征，要求接收端相关解调用一定的机制来近似每个子信道的信道特征。 - The conclusion is identified by computer simulation . the paper studies a noncoherent demodulation based on differential encoding in mc - cdma system and makes computer simulation of ber performance compared with that of coherent demodulation based on perfect channel estimation
研究分析了一种使用差分编码的非相干接收mc - cdma系统，对频率选择性瑞利衰落信道条件下的误码率性能进行了计算机仿真，并且和基于理想信道估计的相干解调方案进行了比较。 - Following this , the thesis research digital demodulation of qpsk and analyze the digitalizing means of key module . digitalizing demodulation arithmetic is given . the thesis also researched in phase ambiguity of coherent demodulation , and then brings forward a new method for settling phase ambiguity
而后研究了qpsk的数字化解调，分析了关键模块的数字化方法，给出了数字化解调算法，并研究了相干解调中的相位模糊问题，提出了一种解决相位模糊的新方法。
