| 摘 要： | 综合幅度量化和相位量化数字射频存储器(DRFM)的性能,提出了一种基于幅相量化的数字储频系统.给出了系统的原理及特点,并对基于幅相量化的DRFM及其调相和调频干扰等进行了仿真.结果表明:与幅度量化和相位量化DRFM相比,幅相量化DRFM在保证高保真度的同时,可大幅减少数据存储量,且有干扰时的相位调制较简单.

| Abstract: | A new method of digital radio frequency memory(DRFM) using amplitude-phase quantizing was put forward in this paper,which integrated classical amplitude quantizing DRFM and phase quantizing DRFM.The principle and characteristics of the amplitude-phase quantizing DRFM were given out.The simulation of amplitude quantizing DRFM,phase quantizing DRFM,amplitude-phase quantizing DRFM and amplitude-phase quantizing DRFM with jamming of phase-modulating and frequency-modulating were done.The results showed that amp... |
