Hi all,
I am still new to GNU radio and still trying to grasp a
complete understand of what each block does.I am trying to
implement simple BPSK mod in GRC. I currently don't have the
USPR I will be using and am trying to simulate the modulation
only in software. I've read up on different ways to implement
BPSK, some of which include modifying the blocks code which
I'd rather not have to do.
Currently I am trying to use the PSK block. I have a random
source generator (type: char) that feeds into the PSK block. I
am using the QTGUIs to plot the output of the PSK mod however
it is not the correct sinusoidal waveform with 180 degree
phase shift. Is there a step I am missing? Or will the
filtering in the PSK block not allow me to get the correct
signal? If so is there a way to "counter-act" the filtering
instead of having to modify the blocks code?
