摘要

采用变码率调制解调器，分析了合成器噪声对数字无线电系统性能的影响。采用A /spl Sigma/-Delta锁相环方法优化合成器相位噪声。为了确定该参数在该系统中的贡献，给出了不同符号率下的积分相位噪声的比较。实验结果表明，该合成器对调制解调器的综合相位噪声具有明显的抑制作用。

A /spl Sigma/-Delta synthesizer phase noise optimization for multi-symbol rate digital microwave radio

The effect of synthesizer noise on digital radio systems performances, using a variable symbol rate modem, is analyzed. A /spl Sigma/-Delta PLL approach is used to optimize the synthesizer phase noise. In order to establish the contribution of this parameter in such systems, a comparison of integrated phase noise for different symbol rates is given. Experimental results show the advantage of a proposed synthesizer on the integrated phase noise see through the modem.
