Hello, this is Hyundai Mobis corporation.
We've been looking up 25C factory calibration for controlling Rx gain/phase mismatch offsets and noise power threshold and loop back power.
Especially, Rx gain decreases significantly with increasing temperature so we have checked some documents related to calibration for temperature trying to implement it.
What we've found out till now is that temperature compensated Rx gain using loop back power is shown below and look up table containing Rx gain information according to temperature exists in the code.
Rx Gain [temperature compensated] = Rx Gain [reported] - (-38 dBm) + Loop back power (temperature)
However, the Rx gain look up table from rlRxGainTempLutData shown below is not implemented and there is no information about Rx gain code.
What we need to know is how this Rx gain code works and which part in the code we can check for reprogramming it.
Also, how this look up table is used after being called.
Thanks,
Seokhyun
