Yes. BPSK Mapper is custom block though it isn't written by me.Both encoders
and decode objects parallelism level are defined as 1. Actually when I rebuild
the flow graph, connect each block in turn, it runs in the first time but then
comes back to that situation.

Hi Mostafa,
it's like you understand: It's the same output buffer, but each
consumer (== block2 and 3) have their own buffer readers that keep
track of how many samples they consumed.
Block 1 can only overwrite parts of the buffer that *both* readers
Hello GNURadioers!
I have a block (blck #1) connected to multiple of blocks. Here I have two
blocks' (call blck #2 and blck #3) connected to blck #1 output.
I'm confused when I saw nitems_read of blck #2 and #3 aren't the same, say
1000 items are read by blck #2 and 155000 items read by blck #3 a
Brad:
You are treating an FFT as if it were a spectrum analyzer which produces a
magnitude or energy profile of how much signal is at a particular
frequency. The FFT does much more than that. It tells not only what
magnitude is at a frequency but what phase angle the signal has there.
Let's tak
Zhe, every single developer who has ever written for GnuRadio runs into
this particular swig necessity and searches like mad, certain it is done...
Congrats.

Can you perform the alignment prior to the but comparison stage? This would simplify the comparison so that it can focus on BER alone and no alignment tasks. It would also address the following:Another issue that may arise if the bits streams are not aligned during comparison is that as you slide t
