SNR-and Rate-Optimized LDPC Codes for Free-Space Optical Channels

We use a low-density parity-check (LDPC) code to mitigate the effects of fluctuations caused by atmospheric turbulence in an uncorrelated flat free-space optical (FSO) channel. To achieve the threshold close to the FSO channel's capacity, we require an optimum degree distribution for the LDPC c...
