802.11 Reference Design

Hello,

I have a question when I run the 802.11 reference design' channel estimate view example. When I check the data in MATLAB, I found that the values of rx_entries.flags in MATLAB do not correspond to the value as shown in http://warpproject.org/trac/wiki/802.11 … ntry_types after transmitting from Hexadecimal to decimal. The flags value in MATLAB is as shown in the figure https://upload.cc/i1/2018/12/05/qUySOw.png

Thus, I want to know what does the value in MATLAB means?

Regards,
Yan

Re: 802.11 Reference Design

The RX_OFDM flags values are bitwise OR'd to compute the value of the flags field. So decimal 193 = 0xC1 = (LTG | LTG_PYLD | FCS_GOOD), indicating the reception was an LTG packet received with a good checksum.
