Ali, S. A.Kambo, N. S.İnce, E. A.2016-02-082016-02-0820071089-7798http://hdl.handle.net/11693/23463This letter presents derivation for an exact and efficient expression on pairwise error probability over fully interleaved Nakagami-m fading channels under ideal channel state information at the decoder. As an outcome, this derivation also leads to a tight upper bound on pairwise error probability which is close to the exact expression. Pairwise error probability plots for different values of Nakagami parameter m along with an already existing numerically computable expression are provided. As an application of pairwise error probability, average union upper bounds for turbo codes having (1, 7/5, 7/5) and (1, 5/7, 5/7) generator polynomials employing transfer function approach are presented to illustrate the usefulness of the new efficient results. © 2007 IEEE.EnglishAverage union upper boundIdeal channel state informationNakagami-m fading channelPairwise error probabilityTurbo codesChannel state informationDecodingFading channelsPolynomialsTransfer functionsAverage union upper boundNakagami parameterPairwise error probabilityTurbo codesArticle10.1109/LCOMM.2007.0700821558-2558
