DOI: 10.1109/TIT.2012.22332710018-9448http://hdl.handle.net/10230/36018This paper determines the range of feasible values of standard error exponents for binary-input memoryless symmetric channels of fixed capacity C and shows that extremes are attained by the binary symmetric and the binary erasure channel. The proof technique also provides analogous extremes for other quantities related to Gallager's E 0 function, such as the cutoff rate, the Bhattacharyya parameter, and the channel dispersion.application/pdfeng© 2013 IEEE.
