Hi,

I am currently working on the mrr_beamforming demo.

I saw some known issues, and I want to understand the difficulties and bottlenecks of mrr_beamforming.

Hi Jitendra,

I want to know why the USRR mode and MRR mode cannot work.

And why only MRR has correct output in USRR/MRR mode?

Thanks

Hello Yunlong,

MRR demo in TI-Rex Lab directory uses advframe config, where each alternate sub-frame is for MRR and USRR. Thus both of these features / modes are supported in MRR at alternate sub-frame

Hello Yunlong,

These are the limitations of the MRR Beamsteering lab. These limitations are due to the use of HWA for the USRR processing.

If the beam-steering and use of HWA are not required, then use the “MRR Lab7” for the developments.

Jitendra
