FPGA Implementation of Stair Matrix based Massive MIMO Detection
Shahriar Shahabuddin, Mahmoud A. Albreem, Mohammad Shahanewaz Shahabuddin +2
Approximate matrix inversion based methods is widely used for linear massive multiple-input multiple-output (MIMO) received symbol vector detection. Such detectors typically utiliz…
Leveraging Location Information for RIS-aided mmWave MIMO Communications
Jiguang He, Henk Wymeersch, Markku Juntti
Location information offered by external positioning systems, e.g., satellite navigation, can be used as prior information in the process of beam alignment and channel parameter es…
Passive RIS vs.Hybrid RIS: A Comparative Study on Channel Estimation
Rafaela Schroeder, Jiguang He, Markku Juntti
The reconfigurable intelligent surface (RIS) plays an important role in maintaining the connectivity in millimeter wave (mmWave) MIMO systems when the direct channel between the tr…
Channel Modeling and Performance Analysis of Airplane-Satellite Terahertz Band Communications
J. Kokkoniemi, J. M. Jornet, V. Petrov +2
Wireless connectivity in airplanes is becoming more important, demanded, and common. One of the largest bottlenecks with the in-flight Internet is that the airplane is far away fro…
Matrix Decomposition for Massive MIMO Detection
Shahriar Shahabuddin, Muhammad Hasibul Islam, Mohammad Shahanewaz Shahabuddin +2
