Hi everyone,
I'm doing a project on joint decode. But my problem is that in the lab
environment, the benchmark transmission is always good, there are hardly any
packet loss, so I can not show the advantage of joint decode.
I've tried to change the physical distance from transmission to receiver
attenna. Still works really well even put in opposite side of the building.
I've tried to change the transmission power and transmission rate. Inspired by
some previous study, I learned that transmission power is controlled by
-tx-amplitude and -tx-gain, in which -tx-amplitude sets the amplitude of the
signal going into the DAC. RF gain is applied in the daughtercard once the
signal has been up converted. Now I'm using 0.2 amplitude and 35 gain. But I
don't understand, how come that the smaller the power is, the better
transmission performance there will be. And also, why does power should be in
the range of 0 to 1.0? How to calculate transmission power using the
-tx-amplitude and tx-gain?
Is there any other way that may cause more error in transmission beside the
ones I mentioned?
Thanks in advance! Any suggestion will be greatly appreciated!
Ada
