WebI/Q origin offset is an interference caused by crosstalk or DC offset. It is an interference of approximately constant amplitude and independent of the amplitude of the wanted signal. … WebMar 30, 2024 · In our work the impact of added I and Q origin offsets to the jamming signal is only investigated. The local oscillator (LO) or Carrier feed-through, sometimes called Origin Offset, can be caused by: The two mixers in the analog stage not being perfectly balanced and matched, resulting in LO leakage. This error is dependent on carrier frequency.
