摘要
为了提高基于CORDIC算法NCO的无杂散动态范围,提出采用相位映射和相位抖动技术来提高无杂散动态范围。SIMULINK仿真结果表明改进后的NCO无杂散动态范围提高近10 dB,充分说明了该方法的可行性。
In order to improve the SFDR of numerically controlled oscillator based on CORDIC algorithm,this paper pro- poses to use phase mapping and phase dither methods to improve the SFDR.Simulation by SIMULINK indicated that the SFDR of this modified NCO structure got 10 dB improvement,fully proves the feasibility of this method.
