| Abstract: | This paper first introduces RS code as the channel code of ALC.Then,it discusses the error performance through PPM and RS code in Gauss channel and weak turbulence channel,and compares the error performance in the system with RS code with the uncoded system.The simulated results indicate that introduction of RS code can get the code gain of 2~3 dB,and error performances under Gauss channel are better than those under weak turbulence channel. |
