Re: [Discuss-gnuradio] FEC Examples with Modulators

Hi Alex -

Have you tried any of the examples in gr-fec/examples? If so and they didn't work for you, what issues have you encountered?

Cheers,

Ben

Hello GNURadio Users,

I'm learning about convolutional encoders in school and would like to
demonstrate their use in gnuradio for a presentation. The examples
appear useful for showing BER and Encoding -> decodng, but I'm
struggling to implement a signal chain

tx_bytes --> unpacked to packed -> FEC_ENCODE -> modulation -> AWGN
channel -> demod -> FEC_DECODE -> received_bytes

I'm not sure where to put the fec_decode on receiver side or how the
bytes need to packed to use it. Are there some tutorials or examples
that FEC with tx to rx (either w/ hardware or loopback)?

Thanks
Alex.
