Short Packets over Block-Memoryless Fading Channels: Pilot-Assisted or Noncoherent Transmission?
Johan Östman, Giuseppe Durisi, Erik G. Ström +2
We present nonasymptotic upper and lower bounds on the maximum coding rate achievable when transmitting short packets over a Rician memoryless block-fading channel for a given requ…
On Out-of-Band Emissions of Quantized Precoding in Massive MU-MIMO-OFDM
Sven Jacobsson, Giuseppe Durisi, Mikael Coldrey +1
We analyze out-of-band (OOB) emissions in the massive multi-user (MU) multiple-input multiple-output (MIMO) downlink. We focus on systems in which the base station (BS) is equipped…
Nonlinear Precoding for Phase-Quantized Constant-Envelope Massive MU-MIMO-OFDM
Sven Jacobsson, Oscar Castañeda, Charles Jeon +2
We propose a nonlinear phase-quantized constant-envelope precoding algorithm for the massive multi-user (MU) multiple-input multiple-output (MIMO) downlink. Specifically, we adapt…
Linear Precoding with Low-Resolution DACs for Massive MU-MIMO-OFDM Downlink
Sven Jacobsson, Giuseppe Durisi, Mikael Coldrey +1
We consider the downlink of a massive multiuser (MU) multiple-input multiple-output (MIMO) system in which the base station (BS) is equipped with low-resolution digital-to-analog c…
Demodulation and Detection Schemes for a Memoryless Optical WDM Channel
Kamran Keykhosravi, Morteza Tavana, Erik Agrell +1
It is well known that matched filtering and sampling (MFS) demodulation together with minimum Euclidean distance (MD) detection constitute the optimal receiver for the additive whi…
Bounds on the Per-Sample Capacity of Zero-Dispersion Simplified Fiber-Optical Channel Models
Kamran Keykhosravi, Giuseppe Durisi, Erik Agrell
A number of simplified models, based on perturbation theory, have been proposed for the fiber-optical channel and have been extensively used in the literature. Although these model…
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…
Common-Message Broadcast Channels with Feedback in the Nonasymptotic Regime: Full Feedback
Kasper Fløe Trillingsgaard, Wei Yang, Giuseppe Durisi +1
We investigate the maximum coding rate achievable on a two-user broadcast channel for the case where a common message is transmitted with feedback using either fixed-blocklength co…
Beta-Beta Bounds: Finite-Blocklength Analog of the Golden Formula
Wei Yang, Austin Collins, Giuseppe Durisi +2
It is well known that the mutual information between two random variables can be expressed as the difference of two relative entropies that depend on an auxiliary distribution, a r…
Finite-Blocklength Bounds on the Maximum Coding Rate of Rician Fading Channels with Applications to Pilot-Assisted Transmission
Johan Östman, Giuseppe Durisi, Erik G. Ström
We present nonasymptotic bounds on the maximum coding rate achievable over a Rician block-fading channel for a fixed packet size and a fixed packet error probability. Our bounds, w…
Short Codes with Mismatched Channel State Information: A Case Study
Gianluigi Liva, Giuseppe Durisi, Marco Chiani +2
The rising interest in applications requiring the transmission of small amounts of data has recently lead to the development of accurate performance bounds and of powerful channel…
