调相信号 meaning in English
phase modulated signal
phase-modulated signal
phse-modulated signals
Examples
- A digitizing demodulation method of pm signal
调相信号的数字化解调 - A phase - locked receiver applied to receive pulsed psk radio frequency
用于接收脉冲射频调相信号的锁相接收机 - The interference and its processing method of long sequence phase - modulation signal of multitargets in pulse compression are studied emphatically
重点研究了长序列调相信号多目标对脉冲压缩的相互影响及其处理方法。 - As for the m - ary psk signals , the differential phase peaks at the transients are used . the pdf ( probability density function ) of the differential phase peaks of m - ary psk are the mean of m - 1 pdfs of m - 1 phase peaks
由于进制的数字调相信号每个子码间具有个相位突变，其相位突变的峰值满足一个概率密度为的分布，若信号为元psk信号，则相位突变峰值的概率密度函数就是个概率密度之和的平均。 - Firstly , on the base of analyzing psk ' s theory and audio - card ' s constitute and data transfers , bdpsk and qdpsk soft - modulation and soft - demodulation systems based on audio - card are studied and implemented , including generating digital carrier sequence , synchronizing carrier , designing filter , sampling and judging , etc . the system adopts coherent demodulation method , synchronizing carrier adopts costas loop
本文首先分析了调相信号调制解调的基本理论和多媒体计算机( mpc )声卡组成原理及数据传输等方面的内容，然后研究并实现了基于计算机声卡的bdpsk和qdpsk信号软件调制解调系统，内容包括数字载波序列的产生、载波同步、滤波器设计，信号的抽样判决等。
