The Expurgated Error Exponent is Not Universally Achievable
Seyed AmirPouya Moeini, Marco Dalai, Albert Guillén i Fàbregas
We study the universal attainability of the expurgated error exponent for discrete memoryless channels (DMCs). While the random-coding exponent is known to be universally attainabl…
Two-Class Joint Source-Channel Coding: Expurgated Exponents with i.i.d. Distributions
Seyed AmirPouya Moeini, Albert Guillén i Fàbregas
This paper studies expurgated exponents for joint source-channel coding of discrete memoryless sources and channels under i.i.d. random coding. We show that a two-class partitionin…
Class-Based Expurgation Attains Csiszár's Expurgated Source-Channel Exponent
AmirPouya Moeini, Albert Guillén i Fàbregas
This paper studies expurgated error exponents for joint source-channel coding for discrete memoryless sources and channels. We consider a partition of the source messages into clas…
Dual-Domain Exponent of Maximum Mutual Information Decoding
AmirPouya Moeini, Albert Guillén i Fàbregas
This paper provides a dual domain derivation of the error exponent of maximum mutual information (MMI) decoding with constant composition codes, showing it coincides with that of m…
