In 2018 52nd Annual Conference on Information Sciences and Systems (CISS)978-1-5386-0579-0https://hdl.handle.net/10016/28846This paper has been presented at: 52nd Annual Conference on Information Sciences and Systems (CISS)Saddlepoint approximations of the meta-converse and random-coding union bounds are derived. These bounds accurately characterize the channel coding minimum error probability for symmetric memoryless channels in a wide range of system parameters. The proposed approximations are simple to compute and yield a unified analysis of both hypothesis-testing lower bounds and random-coding upper bounds.6eng© 2019 IEEE.conference paperTelecomunicacioneshttps://doi.org/10.1109/CISS.2018.8362304open access2018 52nd Annual Conference on Information Sciences and Systems (CISS)CC/0000029965
