Code spectrum and reliability function: Gaussian channel

Published 5 Jun 2007 in cs.IT and math.IT | (0706.0682v1)

Abstract: A new approach for upper bounding the channel reliability function using the code spectrum is described. It allows to treat both low and high rate cases in a unified way. In particular, the earlier known upper bounds are improved, and a new derivation of the sphere-packing bound is presented.
