Analysis and Design of Partially Information- and Partially Parity-Coupled Turbo Codes
Min Qiu, Xiaowei Wu, Alexandre Graell i Amat +1
In this paper, we study a class of spatially coupled turbo codes, namely partially information- and partially parity-coupled turbo codes. This class of codes enjoy several advantag…
Position Information from Single-Bounce Reflections
Anastasios Kakkavas, Mario H. Castañeda García, Gonzalo Seco-Granados +3
In the context of positioning a target with a single-anchor, this contribution focuses on the Fisher information about the position, orientation and clock offset of the target prov…
Power Allocation and Parameter Estimation for Multipath-based 5G Positioning
Anastasios Kakkavas, Henk Wymeersch, Gonzalo Seco-Granados +3
We consider a single-anchor multiple-input multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM) system with imperfectly synchronized transmitter (Tx) and receiv…
Predictor Antenna: A Technique to Boost the Performance of Moving Relays
Hao Guo, Behrooz Makki, Dinh-Thuy Phan-Huy +3
In future wireless systems, a large number of users may access the networks via moving relays (MRs) installed on top of vehicles. One of the main challenges of MRs is rapid channel…
Finite-Alphabet Wiener Filter Precoding for mmWave Massive MU-MIMO Systems
Oscar Castañeda, Sven Jacobsson, Giuseppe Durisi +2
Power consumption of multi-user (MU) precoding is a major concern in all-digital massive MU multiple-input multiple-output (MIMO) base-stations with hundreds of antenna elements op…
Soft-Output Finite Alphabet Equalization for mmWAVE Massive MIMO
Oscar Castañeda, Sven Jacobsson, Giuseppe Durisi +2
Next-generation wireless systems are expected to combine millimeter-wave (mmWave) and massive multi-user multiple-input multiple-output (MU-MIMO) technologies to deliver high data-…
Finite-Alphabet MMSE Equalization for All-Digital Massive MU-MIMO mmWave Communication
Oscar Castañeda, Sven Jacobsson, Giuseppe Durisi +2
We propose finite-alphabet equalization, a new paradigm that restricts the entries of the spatial equalization matrix to low-resolution numbers, enabling high-throughput, low-power…
Predictor Antennas for Moving Relays: Finite Block-length Analysis
Hao Guo, Behrooz Makki, Tommy Svensson
In future wireless networks, we anticipate that a large number of devices will connect to mobile networks through moving relays installed on vehicles, in particular in public trans…
Novel High-Throughput Decoding Algorithms for Product and Staircase Codes based on Error-and-Erasure Decoding
Alireza Sheikh, Alexandre Graell i Amat, Alex Alvarado
Product codes (PCs) and staircase codes (SCCs) are conventionally decoded based on bounded distance decoding (BDD) of the component codes and iterating between row and column decod…
Multi-Server Weakly-Private Information Retrieval
Hsuan-Yin Lin, Siddhartha Kumar, Eirik Rosnes +2
Private information retrieval (PIR) protocols ensure that a user can download a file from a database without revealing any information on the identity of the requested file to the…
An Error-limited NOMA-HARQ Approach using Short Packets
Behrooz Makki, Tommy Svensson, Michele Zorzi
In this paper, we propose and analyze an error-constrained data transmission approach for uplink communication using non-orthogonal multiple access (NOMA). The results are presente…
Refined Reliability Combining for Binary Message Passing Decoding of Product Codes
Alireza Sheikh, Alexandre Graell i Amat, Gianluigi Liva +1
We propose a novel soft-aided iterative decoding algorithm for product codes (PCs). The proposed algorithm, named iterative bounded distance decoding with combined reliability (iBD…
