[Discuss-gnuradio] Verifying Turbo encoder output (was: Re: (no subject))

[Marcus Müller]

Dear Salija,

convolutional encoders are hard to check by hand. Typically, you'd try to decode to verify.
PCCCs can be made systematic, I'm not sure that's the case for the GNU Radio implementation.

Regarding the interleaver: turbocodes rely on adding redundancy calculated from the input data stream, and an permutated version of that. That permutation is done by the interleaver. Without the interleaver, you'd just have two times the same information added as redundancy, and that wouldn't really be an advantage over just using a simple convolutional code that adds twice the redundancy.

Best regards,
Marcus

Hello all,

      I am working with turbo encoder and decoder. is there any method to check and verify the output of pccc encoder.  I want to see the the output of pccc encoder for corresponding binary input. is there any way to do this?

also any body can help me to explain interleaver operation in pccc encoder?

Thanks in advance
