    Hi Tae-hoon,

    Your data looks perfect. The I and Q data should be the same data, just 90° out of phase. You can see that your red and blue data is exactly 90° out of phase (blue peaks when red is midscale). To extract the I and Q baseband data, you will need to digitally demodulate the signal to baseband.
