1. A method of operating a network node of a communication network, the method comprising:
receiving, by a first decoder of the network node, a first upstream-processed signal associated with an original signal;
receiving, by a second decoder of the network node, a second upstream-processed signal, associated with the original signal;
determining, by the first decoder of the network node, a first downstream-processed signal based on the first upstream-processed signal;
responsive to determining the first downstream-processed signal, outputting, by the first decoder, the first downstream-processed signal;
responsive to the first decoder outputting the first downstream-processed signal, determining, by the second decoder of the network node, a second downstream-processed signal based on the second upstream-processed signal and the first downstream-processed signal;
responsive to determining the second downstream-processed signal, outputting, by the second decoder, the second downstream-processed signal;
determining a decoded received signal based on outputs from the first decoder and the second decoder,
responsive to the second decoder outputting the second downstream-processed signal, determining, by the first decoder, a first revised downstream-processed signal based on the first downstream-processed signal and second downstream-processed signal; and
responsive to determining the first revised downstream-processed signal, outputting, by the first decoder, the first revised downstream-processed signal.
