Hello all!
I wrote a script in python that takes a binary file (output of the
usrp_rx_cfile.py), convert it in a sequence of complex values and applies a
variable threshold in order to convert that complex sequence in a square wave.
The complex sequence already represent a square wave, but with a noise and
distortions that I want to clean.
Now I would like to merge what I've done with the gnuradio language, and this is
what I tried:
class my_top_block(gr.top_block):
def __init__(self):
gr.top_block.__init__(self)
def block_cplx_to_sq (matrice):
output1 = []
d = ds = 0;
de = len(matrice);
while (d < de):
[sequence of 'if..else' to find the correct value of [min,max]]
threshold = mean(matrice[min,max]);
stad = std(matrice[min_std,max_std]);
if stad <= 50:
threshold = threshold - 100;
soglia_f.append(threshold);
if abs(matrice[d]) >= threshold:
output1.append(1);
else:
output1.append(0);
d = d + 1;
return output1;
src = gr.file_source(gr.complex, "Acq_petit", TRUE)
BLCK = block_cplx_to_sq ();
self.connect(src, BLCK)
The problem is that the program still requires something as input of
block_cplx_to_sq (and it should be the output of the file_source...).
Does anyone have any idea to help me? (maybe some gnuradio function that I don't
know that does something like this)
Thank you in advance,
Kind regards,
Marco
