signal carrier meaning in English

信号载波

Research on ds bpsk signal carrier estimation methods
信号载频估计方法的研究
How to understand the correlation of parameters and its influence in communication system is the essential task in the research of communication system . through carrying on research and analysis to various kinds of adaptive algorithms , this paper is focus on the application of the algorithm in demodulation in the digital signal carrier transport . the dpsk signals demodulation basing on adaptive algorithm is improved on and a new method is presented for qdpsk and qam signals demodulation by adaptive filter
简单分析讨论了ask 、 fsk的自适应解调方法,由于本研究的战术电台中信号处理采用的是psk方式,所以本文重点研究了利用ndlms算法对dpsk信号的解调方法,并且结合调制信号中正交载波的特点,提出了qdpsk信号自适应解调方法,在提出上述方法后,本文通过仿真进行了验证。
