.Pairwise codeword error probability for coded atmospheric optical communication systems[J].Optoelectronics Letters,2006,2(3):203-205 Pairwise codeword error probability for coded atmospheric optical communication systems HAN Jia-jia RONG Jian ZHONG Xiao-chun [1]College of Science, Southwest Jiaotong University, Chengdu 610031, China [2]College of Physics Electron, University of Electronic Science and Technology of China, Chengdu 610054, China Abstract:       To study the performance of various error-control coding schemes, exact expressions and upper bounds on the pariwise codeword error probability (PEP) for several modulation schemes (OOK, SC-BPSK, BP-PM) used in atmospheric optical communication systems are derived. to simplify the computation, this research was under the assumption of weak turbulence. Moreover, by simulation of expressions, the performances of PEP in different modulation schemes are compared and the best one of them is given.
