Part Number: MMWCAS-RF-EVM

Hello, I am using MMWCAS-RF-EVM and now I have two problems, 1. I need to transmit a large number of chirp in one frame, in theory, I can set numchirp=512,numloop=255, but once my configuration exceeds numchirp=12,numloop=128, the data will be distorted and the received signal will be severely distorted. I'm sending a lot of chirp. How do I configure it so that the data isn't distorted? 2. Frames will be lost from time to time, I set 1000 frames but only receive 900 frames, how should I configure to ensure that I do not lose frames?

Hi Chen,

Thanks for reaching out to us over E2E.

Please find my below questions -

1) How often the data distortion is happening? Is it every time or after some time you're seeing this?

2) Are you using mmWave Studio or the OOB Demo for your test for both the cases?

3) What type of data distortion are you facing? How are you verifying if your data is incorrect?

4) How often are you facing the frame loss? Have you checked with lesser or higher number of frames?

Regards,
Anirban

Yeah, it happens every time

2) Are you using mmWave Studio or the OOB Demo for your test for both the cases?

I use mmWave Studio

3) What type of data distortion are you facing? How are you verifying if your data is incorrect?

After rangefft, I observed a frame of data through surf on matlab, and some chirp amplituates were particularly large, while some chirp amplituates were particularly small.
