The last step in the process of producing phase-independent decoding results is to combine the I and Q offsets into a single decoding value. This can be done as follows: Webb8 okt. 2024 · For DC-offset minimization a hybrid method based on AC coupling with very low cut-off frequency and DAC-controlled hardware balancer of ADC inputs was developed. The level of the DC component in the output spectrum after calibration is close to -70 dBFS.
WebbActually, I have used the RF Budget Analyzer designing a direct conversion receiver, and then by 'exporting to testbench in RF blockset', I've got a RF Measurement Testbench as below: After that I use this testbench to test the DC offset of my receiver, my question is that I want to know how the DC offset is measured.
