Performance of multiple-input multiple-output wireless communications systems using distributed antennas

open access: yes, 2005
In this contribution we propose and investigate a multiple-input multiple-output (MIMO) wireless communications system, where multiple receive antennas are distributed in the area covered by a cellular cell and connected with the base-station (BS).

A SURVEY INTO ESTIMATION OF LOGNORMAL DATA

open access: yes, 2010
Lognormal data are very difficult to handle because of its high variability due to the occurrence of a few high values. In geostatistics the solution calls for a data transform, such as the logarithm transform and the indicator transform. Both approaches
