把I、Q 两路信号分别作FFT ,找出频域内信号的幅度,即可算得两路分量的幅度一
％致性 把I、Q两路信号合成一个复数信号,作FFT ,对得到的频谱求镜像抑制比。-The I, Q signals, respectively, for the two FFT, to identify the range of frequency domain signal can be considered two-way range of 1 weight of the letter I, Q synthesis of two-way signal a plural signal for FFT, to obtain the spectrum for image rejection ratio.
