Hello,

I'm using a DEMO BGT60TR13C board with Raspberry Pi 4 and receiving data on all 3 receivers, but Rx1 data is getting clipped with all the Chirps for a few sampling points, why is this happening? Please see the data below and the configuration. I have no problem with Rx2 & Rx3 receivers. Thank you!

Hello @hj2,

The starting samples are skipped to avoid leakage. The lower frequency bins (lower ranges) have some leakage offset since the Tx-Rx coupling kicks in. These effects can be mitigated with compensation algorithms. The SDK demo examples don't use the compensation algorithms So, the lower range is omitted from processing, in order to use a simple program to demonstrate the working. This is the reason why you may notice some missing samples.
 
Best Regards,
Pugitha.
