LAUNCHXL-CC26X2R1: AoA angle calculation from IQ samples

LAUNCHXL-CC26X2R1: AoA calculation examples

Hi,

I would appreciate if someone could link me to examples or previous developments where AoA has been calculated from the IQ samples generated in rtls_agent examples, or something similar just regarding IQ samples. I know there are different implementations and algorithms when it comes to AoA, but it would help to have a frame of reference from similar developments.

Thank you.

    Hi,

    You can refer to the embedded code in SDK 5.10. There, AOA calculation is made on the CC2642R device. You'll find the algorithm in the file Drivers\AOA\AOA.c of the rtls_master example.

    I have to tell you the algorithm used there suffers a lot from the effects of multipath. In other words, this algorithm works well in an anechoic chamber but may not provide the expected result in a real environment. This is the only algorithm I can point you to.

    I hope this will help,

    Best regards,
