Mismatch Capacity under Stochastic Decoding

Francesc Molina, Albert Guillen i Fabregas

This manuscript investigates channel capacity under mismatched stochastic likelihood decoding. We derive Feinstein- and Verdú-Han-style bounds on the error probability coded commun…

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…

Generalized Random Gilbert-Varshamov Codes: Typical Error Exponent and Concentration Properties

Lan V. Truong, Albert Guillén i Fàbregas

We find the exact typical error exponent of constant composition generalized random Gilbert-Varshamov (RGV) codes over DMCs channels with generalized likelihood decoding. We show t…

Concentration Properties of Random Codes

Lan V. Truong, Giuseppe Cocco, Josep Font-Segura +1

This paper studies the concentration properties of random codes. Specifically, we show that, for discrete memoryless channels, the error exponent of a randomly generated code with…

A Sphere-Packing Error Exponent for Mismatched Decoding

Ehsan Asadi Kangarshahi, Albert Guillén i Fàbregas

We derive a sphere-packing error exponent for coded transmission over discrete memoryless channels with a fixed decoding metric. By studying the error probability of the code over…

Minimum Probability of Error of List M-ary Hypothesis Testing

Ehsan Asadi Kangarshahi, Albert Guillen i Fabregas

We study a variation of Bayesian M-ary hypothesis testing in which the test outputs a list of L candidates out of the M possible upon processing the observation. We study the minim…
