I am new to FEC (Forward Error Correction). Pointers highly appreciated.
I am experimenting software with configurable "error protections". Result improving as setting raise to 40%. Still not enough 'margin'. The software uses Reed Solomon inside.
Experiemntal data suggests, 'subjective performance' should be good at "60% to 200%". Speed is no issue. We can afford adding extra bits to raise transmission success rate.
a) Does Reed Solomon code has good scalable improvement over high number of reduanant bits? I believe many FEC schemes use 30% extra bits and we need much more.
b) Should we try newer Turbo and Low-density parity-check codes. Which one has better proformance at high redundant rate (40% to 200% reduanant bit added)?
c) Where can I get experimental FEC software with high configurable redundant rate (40% to 200%)?
The channel cannot be fully modelled since some of the error sources are human / machine operation allowance, etc. It will be heavy on 'real-life' subjective tests.
