Hello,
I am trying to find a different approach regarding the poor error handling
issue.
My Idea is to write a demodulator from scratch. Instead of either having an
output consisting of approximated values (later to be fed into the FEC
decoder) or having none, we could write the demodulator so that it adds a
"tail" after each symbol so that we have
floating point values in the end. Take this example: The demodulator would
either aproximate a value between 00 and 01 or we would have an error. With
my example, it would output a value between 0000000001 and 0011111111. We
would than use a cognitive decoder to "guess" wich value it should use. I
am aware that a cognitive decoder is not a piece of cake and that we ar
fighting with highly compressed data. But, given the overhead reduction
from the FEC, we should bbe able to get a decent gain. The result in low
SNR should be a noisy output but inteligible, similar to an analog radio
(sort of).
