This paper presents a novel ultrawideband wireless spread spectrum millimeter-wave
(mmWave) channel sounder that supports both a wideband sliding correlator mode and a …

Information theoretic limits for random key generation in multiple-input multiple-output
(MIMO) wireless systems exhibiting a reciprocal channel response are investigated …

Channel measurements are the prerequisite condition for the design of the next-generation
high-speed railway (HSR) communication system. Because of the measurement restriction …

This paper presents a novel multiple-input-multiple-output (MIMO) channel sounding
technique with a fully parallel transceiver architecture that employs a layered scheme of …

Wireless communications have attracted great interest from the industry due to its lower
costs and the possibility of enabling new use cases. The new use cases are commonly …

Interorganizational interactions are often complex and paradoxical. In this research, we
transcend two management paradoxes: competition versus cooperation and open-source …

When establishing secret encryption keys using estimates of the reciprocal wireless
channel, the number of key bits that can be generated for a static or slowly varying …

In order to utilize higher frequency bands above 6GHz, which is an important technical
challenge in fifth generation mobile systems, radio propagation channel properties in a large …

Colocated 4× 4 multiple-input multiple-output measurements at 2.55 and 24 GHz are
presented for two university buildings consisting of classrooms and offices. Link gain in …

This paper presents a characterization of the practical performance gains of a multiple-
