Saddlepoint Approximations for Short-Packet Wireless Communications
Alejandro Lancho, Jöhan Ostman, Giuseppe Durisi +2
In recent years, the derivation of nonasymptotic converse and achievability bounds on the maximum coding rate as a function of the error probability and blocklength has gained atte…
Robust Signaling for Bursty Interference
Grace Villacrés, Tobias Koch, Aydin Sezgin +1
This paper studies a bursty interference channel, where the presence/absence of interference is modeled by a block-i.i.d.\ Bernoulli process that stays constant for a duration of $…
On the Information Dimension of Multivariate Gaussian Processes
Bernhard C. Geiger, Tobias Koch
The authors have recently defined the Rényi information dimension rate of a stationary stochastic process as the entropy rate of the uniform…
On Single-Antenna Rayleigh Block-Fading Channels at Finite Blocklength
Alejandro Lancho, Tobias Koch, Giuseppe Durisi
This paper concerns the maximum coding rate at which data can be transmitted over a noncoherent, single-antenna, Rayleigh block-fading channel using an error-correcting code of a g…
On the Information Dimension of Stochastic Processes
Bernhard C. Geiger, Tobias Koch
In 1959, Rényi proposed the information dimension and the -dimensional entropy to measure the information content of general random variables. This paper proposes a generalizati…
Continuous Transmission of Spatially-Coupled LDPC Code Chains
Pablo M. Olmos, David G. M. Mitchell, Dmitri Truhachev +1
We propose a novel encoding/transmission scheme called continuous chain (CC) transmission that is able to improve the finite-length performance of a system using spatially-coupled…
Canonical correlation analysis of high-dimensional data with very small sample support
Yang Song, Peter J. Schreier, David Ramirez +1
This paper is concerned with the analysis of correlation between two high-dimensional data sets when there are only few correlated signal components but the number of samples is ve…
Converse Bounds for Entropy-Constrained Quantization Via a Variational Entropy Inequality
Tobias Koch, Gonzalo Vazquez-Vilar
We derive a lower bound on the smallest output entropy that can be achieved via vector quantization of a -dimensional source with given expected th-power distortion. Speciali…
The Shannon Lower Bound is Asymptotically Tight
Tobias Koch
The Shannon lower bound is one of the few lower bounds on the rate-distortion function that holds for a large class of sources. In this paper, it is demonstrated that its gap to th…
Short-Packet Communications over Multiple-Antenna Rayleigh-Fading Channels
Giuseppe Durisi, Tobias Koch, Johan Östman +2
Motivated by the current interest in ultra-reliable, low-latency, machine-type communication systems, we investigate the tradeoff between reliability, throughput, and latency in th…
Multi-Class Source-Channel Coding
Irina E. Bocharova, Albert Guillén i Fàbregas, Boris D. Kudryashov +3
This paper studies an almost-lossless source-channel coding scheme in which source messages are assigned to different classes and encoded with a channel code that depends on the cl…
