We focus on MIMO mesh networks, which consist of wireless nodes supporting MIMO transmission. Communication quality of a wireless link using MIMO spatial streams is sensitive to change in its channel, and performance will be unstable. For stable operation of MIMO mesh networks, a method analyzing the MIMO mesh networks is needed. In this paper, we aim to propose an analyzing method of MIMO mesh networks...
In this paper we apply approximate and multiscale entropy metrics to spectrum occupancy data gathered during an extensive measurement campaign. We show that the presented methods can be successfully applied to search for and quantify structures of highly varying complexities and time scales. Although structures can be found they are unfortunately relatively complex and it does not appear to be easy...
This paper investigates the effective gain of antennas in indoor channels. A metric called instantaneous effective gain is proposed, and a multiple-cluster 3D channel model is used to facilitate the proposed antenna effective gain. In the multiple-cluster channel model, Laplacian and double exponential distribution are utilized to model azimuth and elevation signal power distribution respectively,...
