Design of a Numerically Controlled Oscillator(NCO) Based on CORDIC Algorithm 采用CORDIC算法的数控振荡器(NCO)设计
The realization methods of both numerically controlled oscillator ( NCO ) and the shaping filter are introduced in modulator. 调制部分介绍了数字控制振荡器(NCO)和成形滤波器的实现原理。
Thirdly numerically controlled oscillator ( NCO ) and automatically frequency controller ( AFC ) are studied. A new NCO structure is proposed, and the theory and effect of a kind of AFC is studied by simulation. 然后探讨了数控振荡器(NCO)(NCO)和自动频率控制(AFC)的问题,提出了一种新的NCO结构,仿真分析了一种AFC方案的原理及其效果;
The timing recovery in this paper is composed of interpolation, timing error detector, loop filter and numerically controlled oscillator. 本文设计的定时恢复结构包括插值器、定时误差检测器、环路滤波器和数控振荡器(NCO)四部分。
Then we make some efforts to discuss the timing recovery scheme which is composed of interpolator, timing error detector, loop filter and numerically controlled oscillator and do the simulation of the scheme. 对于定时恢复的各个部分:内插器、定时误差检测器、环路滤波器和数控振荡器(NCO)进行了详细阐述,并进行了定时环路的仿真。
