Maximum Ratio Combining

Dear all,

I am using the mrc implemented in gnuradio but my performance does not
improve compared with the case 1TX-1RX.
The parameters and devices are the same in both cases.

Do you have any hint?

Regards,
Vanessa

Really? What’s your performance metric?

Matt and I didn’t do a BER test or anything, but we looked at the
constellations with 1x1 and 1x2 MRC and saw much less variance in noise
with the MRC methods. We had to assume that meant better performance.

Well, I am counting the number of received, lost and wrong packets.
Each packet is 1500 Bytes + header.

I will investigate better the problem. I sent this message to know if
there was any particular parameter that could affect the performance.

How did you compute the BER? So that I can do the same and see the
results.

Thank you for your replay

BR,
Vanessa
