In wireless optical communication,effects of scintillation make average Bit Error Rate (BER) deteriorate.To improve system performance,PCCC (Parallel Concatenated Convolutional Code) encoding scheme is employed,and upper bound on the bit error rate is given by considering the effects of scintillation,APD noise and thermal noise.Simulation results show that the PCCC encoding scheme can relieve turbulence-induced intensity fluctuations and the system performance is improved remarkably.
