RT Conference Proceedings T1 Saddlepoint approximations of lower and upper bounds to the error probability in channel coding A1 Font Segura, Josep A1 Vázquez Vilar, Gonzalo A1 Martínez, Alfonso A1 Guillén I Fàbregas, Albert A1 Lancho Serrano, Alejandro AB 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.
