Massive MIMO testbed - Implementation and Initial Results in System Model Validation
Changchun Zhang, Robert C. Qiu
This paper presents the design and implementation of a novel SDR based massive MIMO testbed with up to 70 nodes built at Tennessee Technological University. The deployment can reac…
The Foundation of Big Data: Experiments, Formulation, and Applications
Robert C. Qiu
The central theme of this talk is to promote the non-asymptotic statistical viewpoint in the context of massive datasets. The classical viewpoint breaks down when the data size bec…
Spectrum Sensing with Small-Sized Datasets in Cognitive Radio: Algorithms and Analysis
Feng Lin, Robert C. Qiu, James P. Browning
Spectrum sensing is a fundamental component of cognitive radio. How to promptly sense the presence of primary users is a key issue to a cognitive radio network. The time requiremen…
Data Modeling with Large Random Matrices in a Cognitive Radio Network Testbed: Initial Experimental Demonstrations with 70 Nodes
Changhun Zhang, Robert C. Qiu
This short paper reports some initial experimental demonstrations of the theoretical framework: the massive amount of data in the large-scale cognitive radio network can be natural…
Modeling Massive Amount of Experimental Data with Large Random Matrices in a Real-Time UWB-MIMO System
Xia Li, Feng Lin, Robert C. Qiu
The aim of this paper is to study data modeling for massive datasets. Large random matrices are used to model the massive amount of data collected from our experimental testbed. Th…
