Near-Far Field Channel Modeling for Holographic MIMO Using Expectation-Maximization Methods

no code implementations15 Jan 2024 Houfeng Chen, Shuhao Zeng, Hao Guo, Tommy Svensson, Hongliang Zhang

However, this gives rise to a new challenge for accurately modeling the channel, as conventional methods of obtaining channel model parameters are not applicable to this model.

6G Positioning and Sensing Through the Lens of Sustainability, Inclusiveness, and Trustworthiness

no code implementations24 Sep 2023 Henk Wymeersch, Hui Chen, Hao Guo, Musa Furkan Keskin, Bahare M. Khorsandi, Mohammad H. Moghaddam, Alejandro Ramirez, Kim Schindhelm, Athanasios Stavridis, Tommy Svensson, Vijaya Yajnanarayana

6G promises a paradigm shift in which positioning and sensing are inherently integrated, enhancing not only the communication performance but also enabling location- and context-aware services.

Beamforming in Wireless Coded-Caching Systems

no code implementations11 Sep 2023 Sneha Madhusudan, Charitha Madapatha, Behrooz Makki, Hao Guo, Tommy Svensson

To that end, we investigate a wireless transport network architecture that integrates beamforming and coded-caching strategies.

Waveforms for sub-THz 6G: Design Guidelines

no code implementations15 Jun 2023 Muris Sarajlić, Nuutti Tervo, Aarno Pärssinen, Le Hang Nguyen, Hardy Halbauer, Kilian Roth, Vaidyanathan Kumar, Tommy Svensson, Ahmad Nimr, Stephan Zeitz, Meik Dörpinghaus, Gerhard Fettweis

The projected sub-THz (100 - 300 GHz) part of the upcoming 6G standard will require a careful design of the waveform and choice of slot structure.

Constrained Deployment Optimization in Integrated Access and Backhaul Networks

no code implementations11 Oct 2022 Charitha Madapatha, Behrooz Makki, Hao Guo, Tommy Svensson

Due to the sensitivity of the backhaul links with high rate/reliability demands, proper network planning is needed to make the IAB network performing appropriately and as good as possible.

Joint Scheduling and Throughput Maximization in Self-backhauled Millimeter Wave Cellular Networks

no code implementations4 Jun 2021 Chao Fang, Charitha Madapatha, Behrooz Makki, Tommy Svensson

Integrated access and backhaul (IAB) networks have the potential to provide high data rate in both access and backhaul networks by sharing the same spectrum.

On Topology Optimization and Routing in Integrated Access and Backhaul Networks: A Genetic Algorithm-based Approach

no code implementations14 Feb 2021 Charitha Madapatha, Behrooz Makki, Ajmal Muhammad, Erik Dahlman, Mohamed-Slim Alouini, Tommy Svensson

In this paper, we study the problem of topology optimization and routing in integrated access and backhaul (IAB) networks, as one of the promising techniques for evolving 5G networks.

Predictor Antenna: A Technique to Boost the Performance of Moving Relays

no code implementations18 Dec 2020 Hao Guo, Behrooz Makki, Dinh-Thuy Phan-Huy, Erik Dahlman, Mohamed-Slim Alouini, Tommy Svensson

In future wireless systems, a large number of users may access the networks via moving relays (MRs) installed on top of vehicles.

Hybrid Precoding in Cooperative Millimeter Wave Networks

no code implementations13 Jan 2020 Chao Fang, Behrooz Makki, Jingya Li, Tommy Svensson

Considering joint transmissions and BS silence strategy, we propose hybrid precoding algorithms which minimize the sum power consumption of the base stations (BSs), for both fully- and partially-connected hybrid precoding (FHP and PHP, respectively) schemes, for single-carrier and orthogonal frequency-division multiplexing systems.
