All-Digital Massive MIMO Uplink and Downlink Rates under a Fronthaul Constraint
Y. Ettefagh, S. Jacobsson, A. Hu +2
We characterize the rate achievable in a bidirectional quasi-static link where several user equipments communicate with a massive multiple-input multiple-output base station (BS).…
Short-Packet Transmission over a Bidirectional Massive MIMO link
Johan Östman, Alejandro Lancho, Giuseppe Durisi
We consider the transmission of short packets over a bidirectional communication link where multiple devices, e.g., sensors and actuators, exchange small-data payloads with a base…
Short-packet Transmission via Variable-Length Codes in the Presence of Noisy Stop Feedback
Johan Östman, Rahul Devassy, Giuseppe Durisi +1
We present an upper bound on the error probability achievable using variable-length stop feedback codes, for a fixed size of the information payload and a given constraint on the m…
Massive MU-MIMO-OFDM Uplink with Direct RF-Sampling and 1-Bit ADCs
Sven Jacobsson, Lise Aabel, Mikael Coldrey +4
Advances in analog-to-digital converter (ADC) technology have opened up the possibility to directly digitize wideband radio frequency (RF) signals, avoiding the need for analog dow…
Timing and Frequency Synchronization for 1-bit Massive MU-MIMO-OFDM Downlink
Sven Jacobsson, Carl Lindquist, Giuseppe Durisi +2
We consider timing and frequency synchronization for the massive multiuser (MU) multiple-input multiple-output (MIMO) downlink where 1-bit digital-to-analog converters (DACs) are u…
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…
Peak-Age Violation Guarantees for the Transmission of Short Packets over Fading Channels
Johan Östman, Rahul Devassy, Giuseppe Durisi +1
We investigate the probability that the peak age of information in a point-to-point communication system operating over a multiantenna wireless fading channel exceeds a predetermin…
Neural-Network Optimized 1-bit Precoding for Massive MU-MIMO
Alexios Balatsoukas-Stimming, Oscar Castañeda, Sven Jacobsson +2
Base station (BS) architectures for massive multi-user (MU) multiple-input multiple-output (MIMO) wireless systems are equipped with hundreds of antennas to serve tens of users on…
Low-Complexity Joint Channel Estimation and List Decoding of Short Codes
Mustafa Cemil Coşkun, Gianluigi Liva, Johan Östman +1
A pilot-assisted transmission (PAT) scheme is proposed for short blocklengths, where the pilots are used only to derive an initial channel estimate for the list construction step.…
