Block-Fading Channels at Finite Blocklength
This tutorial paper deals with the problem of characterizing the maximal achievable rate R∗(n, ) at a given blocklength n and error probability over block-fading channels. We review recent results that establish tight bounds on R∗(n, ) and characterize its asymptotic behavior. Comparison between the theoretical results and the data rates achievable with the coding scheme used in LTE-Advanced ar...
متن کاملFading Channels: Capacity and Channel Coding Rate in the Finite-Blocklength Regime
Information-theoretic studies on the fundamental limits of communication over wireless fading channels typically rely on simplifying assumptions, such as perfect channel state information (CSI), infinite blocklength, and vanishing probability of error. Although these assumptions are reasonable for most of the current wireless communication systems, they may be inaccurate for next-generation wir...
متن کاملPhysical Layer Security for RF Satellite Channels in the Finite-length Regime
Secure communications is becoming increasingly relevant in the development of space technology. Well established cryptographic technology is already in place and is expected to continue to be so. On the other hand, information theoretical security emerges as a post-quantum versatile candidate to complement overall security strength. In order to prove such potential, performance analysis methods...
متن کاملCoherent multiple-antenna block-fading channels at finite blocklength
In this paper we consider a channel model that is often used to describe the mobile wireless scenario: multipleantenna additive white Gaussian noise channels subject to random (fading) gain with full channel state information at the receiver. Dynamics of the fading process are approximated by a piecewise-constant process (frequency non-selective isotropic block fading). This work addresses the ...
متن کاملOn Single-Antenna Rayleigh Block-Fading Channels at Finite Blocklength
This paper concerns the maximum coding rate at which data can be transmitted over a noncoherent, singleantenna, Rayleigh block-fading channel using an error-correcting code of a given blocklength with a block-error probability not exceeding a given value. A high-SNR normal approximation of the maximum coding rate is presented that becomes accurate as the signal-to-noise ratio (SNR) and the numb...
