Hi,
My setup consists of two X310s - one transmitter and one receiver -
connected with SMA cable.
The receiver code has been independently tested by capturing the AP packets.
The transmitter code was tested in a software loopback with the receiver.
The gains on both sides were adjusted such that there was no clipping.
attenuator (-10db) were used to connect the two USRPs over SMA link.
The transmitter transmits the packet but at the receiver end, these
packets are not successfully decoded. A deeper look reveals that for a
high correlation value (0.8) , packets are being detected by the packet
detection mechanism but the signal field is decoded wrongly in all the
packets detected. . Since unit testing of every block was successful, it
was my hypothesis that the source of error lies on the
transmitter-hardware side.
I began scraping thorough the mail archives and got hold of this :

This thread details on the problem related to burst transmissions in
X310. Apparently, the successive bursts are not same - the end of first
burst is appended to the second burst.
I don't have the hardware to verify the claim, but assuming that it is
correct. It still doesn't explain the wrong decoding of the signal field.
