摘      要：Free-space optical(FSO)communication is of supreme importance for designing next-generation *** the past decades,the radio frequency(RF)spectrum has been the main topic of interest for wireless *** RF spectrum is becoming denser and more employed,making its availability tough for additional *** communication,exploited for messages or indications in historical times,is now becoming famous and useful in combination with error-correcting codes(ECC)to mitigate the effects of fading caused by atmospheric turbulence.A free-space communication system(FSCS)in which the hybrid technology is based on FSO and *** is a capable solution to overcome the downsides of current schemes and enhance the overall link reliability and *** proposed FSCS with regular low-density parity-check(LDPC)for coding techniques is deliberated and evaluated in terms of signal-to-noise ratio(SNR)in this *** extrinsic information transfer(EXIT)methodology is an incredible technique employed to investigate the sum-product decoding algorithm of LDPC codes and optimize the EXIT chart by applying curve *** this research work,we also analyze the behavior of the EXIT chart of regular/irregular LDPC for the *** also investigate the error performance of LDPC code for the proposed FSCS.
