A Distance Between Channels: the average error of mismatched channels
Two channels are equivalent if their maximum likelihood (ML) decoders coincide for every code. We show that this equivalence relation partitions the space of channels into a generalized hyperplane arrangement. With this, we define a coding distance between channels in terms of their ML-decoders which is meaningful from the decoding point of view, in the sense that the closer two channels are, t...
متن کاملCapacity of Generalized Mismatched Gaussian Channels
Information capacity is determined for a Gaussian communication channel when the constraint is given in terms of a covariance which is different from that of the channel noise. AMS (M)S) subject classifications (1970): Primary, 94A15, 60G35
متن کاملUnified Analysis of the Average Gaussian Error Probability for a Class of Fading Channels
This paper focuses on the analysis of average Gaussian error probabilities in certain fading channels, i.e. we are interested in E[Q( √ pγ] where Q(·) is the Gaussian Q-function, p is a positive real number and γ is a nonnegative random variable. We present a unified analysis of the average Gaussian error probability, derive a compact expression in terms of the Lauricella F (n) D function that ...

A New Upper Bound on the Average Error Exponent for Multiple-Access Channels
A new lower bound for the average probability or error for a two-user discrete memoryless (DM) multiple-access channel (MAC) is derived. This bound has a structure very similar to the well-known sphere packing packing bound derived by Haroutunian. However, since explicitly imposes independence of the users’ input distributions (conditioned on the time-sharing auxiliary variable) results in a ti...
