In large antenna arrays with a large number of antenna elements, the required number of measurements for the characterization of the antenna array is very demanding in cost and time. This letter presents a new offline calibration process for active a

The use of multiple antennas at each side of the radio link has demonstrated an increase in terms of data bit rate and spectral efficiency [1]. Due to this, different techniques such as spatial multiplexing and space-frequency-time techniques are bei

Multiple-input multiple-output (MIMO) systems have widely been studied in recent years as a solution to improve the radio link reliability. In order to introduce MIMO in mobile communications, it is necessary to design antennas with several features

Dual-polarized antennas have been proposed as an interesting option to implement MIMO systems in realistic user terminals. In order to study the MIMO channel characteristics when multiple polarizations are considered, a measurement campaign was carri

It is well known that impulsive noise may significantly degrade wireless digital communication performance. The authors quantify the BER degradation of W-CDMA signals in the presence of measured impulsive noise interference, and evaluate the performa

Performance of an adaptive antenna array is usually expressed in terms of the average signal-to-interference plus noise ratio increase with respect to a conventional sectored antenna (ΔSINR). A complete statistical characterisation of the ΔSINR per
