Abstract :
We show in this paper the achievable improvement of the coding gain in the reverse link (air-to-ground) for the L-band Digital Aeronautical Communications System if the current forward error correction scheme based on a concatenated Reed-Solomon convolutional code is replaced by either a turbo code or a nonbinary low-density parity-check code for the smallest assignable data block. Additionally to improving the coding gain, the proposed coding schemes enable a fully iterative detection because of their soft-value decoding algorithms. This improves in general the detection process as a whole.
