Embodiment Construction
[0039] The image suppression method of the receiver in the embodiment of the present invention, such as figure 1 shown, including steps:
[0040] Step 1. Input a reference signal to the downlink, and output the reference signal processed by the downlink to the uplink;
[0041] Step 2. Obtain the I / Q data of the reference signal through the uplink processing;
[0042] Step 3, performing autocorrelation and cross-correlation calculations on the I-way data and Q-way data of the reference signal, and calculating the image correction coefficient according to the calculation results;
[0043] Step 4, disconnecting the reference signal input to the downlink;
[0044] Step 5. Correct the I / Q data of the normal signal after the uplink processing according to the image correction coefficient.
[0045] The reason for the mirror image is that the phase and amplitude of the I / Q data are unbalanced. Therefore, the root of image suppression is to balance the IQ data. During specific impl...
