extracting CSI results from two RX antennas #397

Open wuhhaCos opened 2 months ago

wuhhaCos commented 2 months ago

Dear Professor Jiao,

I am currently working on your OpenWiFi project, primarily focusing on CSI extraction. I have encountered a couple of questions:

  1. In the CSI extraction process, does it have to work in the full-duplex (Self-TX) mode? Can we set it as a receiver to obtain CSI?

  2. If full-duplex mode is required, does the CSI extraction process only work for single RX sampling? The hardware platform we used is Xilinx Zed board + FMCOMMS3, which includes two Rx antennas.

  3. If the above options are not available, can I modify the FPGA code in your project to enable the entire module to operate as a receiver for CSI extraction and sample equalizer results from 2 RX?

I am eager to contribute to the OpenWiFi platform and would greatly appreciate your guidance on these matters.

Please find the corresponding GitHub link for reference: CSI Extraction in OpenWiFi

Thank you for your assistance.
