AWR1642: BPM post-processing for interference mitigation

Adam Yao94020

Part Number: AWR1642

Hi Champion,
I see for BPM modulation and post-processing in the receiver side, we have a ticket https://e2e.ti.com/support/sensor/mmwave_sensors/f/1023/p/603800/2224114?tisearch=e2e-quicksearch&keymatch=BPM#2224114

Besides this, do we have updated documents and reference code for BPM processing in AWR1642? Do we have any experiment on this approach for interference mitigation?

Thanks,
Adam

Hi Summeer,
In your attached document section 4.2, there is an introduction of BPM module for +1, -1, +1, -1 for TX2. For interference mitigation, a random PN code should be applied across chirps and the mitigation is achieved by applying different code for different radar. Do we study the approach of this method?

Thanks,
Adam
