Hi, all,
I write a DBPSK modulation/demodulation program in GNU and python. But the main
frame cannot compile correctly. Can you help me to check it? Thanks.
from gnuradio import gr
from gnuradio import audio
from array import array # Array
import wx
import os # Operating System dependent call
import socket # Socket
import sys # System call
import TypeConverterModule # Type converter
import DBPSKMod # DBPSK Modulation
import GMSKMod # GMSK Modulation
# -----------------------------------------
# Function: Read file and return data array
# -----------------------------------------
def ReadFile (arrImg, fpR):
while True:
data = fpR.read(1) # Read data, 1 byte each time
if len(data) == 0: # If reach EOF, finish the loop
break
objTypeConv = TypeConverterModule.TypeConverter()
lData = objTypeConv.char2int(data) # Convert char to int
arrImg.append(lData) # Store data(int) into array
#print lData, ' ',
return arrImg
def OnDBPSK_Modulate(self):
fpR = open('./JpegEncoder/s.dat', 'r')
# Read the data and print
arrImg = array('B') #the array is char
arrImg.append(0) # you know, for the diff encoding stuff
arrImg = ReadFile (arrImg, fpR)
print ' '
print 'Total = ', len(arrImg), 'bytes'
#self.control.SetValue('[Read File] - Finish!')
# -------------------------------------------------------------
# Start to send jpeg file
# -------------------------------------------------------------
# Construct graph
tb = gr.top_block() #cheng
arrImg[0] = 0 # you know, for the diff encoding stuff
bytes_src = gr.vector_source_b(arrImg, False)
objMod = DBPSKMod.dbpsk_mod()
#start DBPSK demoluation
objDemod = DBPSKDemod.dbpsk_demod()
tb.connect(bytes_src, objMod, objDemod)
tb.run()
print "Finished!!!"
if __name__ == '__OnDBPSK_Modulate__':
OnDBPSK_Modulate(self)
