Belief Propagation Decoding of Low-density Parity-check Codes for Atmospheric Turbulent Optical PPM Communication Systems
BP decoding of LDPC code for weak atmospheric turbulent optical PPM systems was studied, and corresponding decoding algorithm was introduced according to the system model. Through theoretical analysis and extensive computer simulations, the result shows that the LDPC coded weak atmospheric turbulent optical PPM system has better BER than the uncoded weak atmospheric turbulent optical PPM system, but the BER performance of the system increases with the increase of slot.
