Hey Jan, Thanks for your reply, you are correct about the bit shift being LSB. So, I reversed the bit order of polynomials 1101101 to 1011011 and 100 to 001 in MATLAB, Now the output of gnuradio and MATLAB and my dry run matches. I am wondering why they did implementation like this? Any ad

[Discuss-gnuradio] Convolutional Code output does not match polynomial

2015-09-01 Thread bob wole
I am trying channel coding in gnuradio. I am using convolutional encoder with K=7 and R=1/2 with polynomials [109, 79] (default). However I am not getting the expected result. I input a known bit sequence, single frame using head block, and observe the output of the encoder using file sink. The out
