.PCCC for the performance improvement of the wireless optical communication system[J].Optoelectronics Letters,2006,2(2):133-135 PCCC for the performance improvement of the wireless optical communication system REN Rui-xiang LI Xiao-feng LIN Mi College of Physical Electronics, University of Electronic Science and Technology of China, Chengdu 610054, China Abstract:       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.
