Abstract

We evaluate two error correction systems based on low-density parity-check (LDPC) codes for free-space optical (FSO) communication channels subject to atmospheric turbulence. We simulate the effect of turbulence on the received signal by modeling the channel with a gamma-gamma distribution. We compare the bit-error rate performance of these codes with the performance of Reed-Solomon codes of similar rate and obtain coding gains from 3 to 14 dB depending on the turbulence conditions.
