A DEVICE FOR IMPROVED ISOLATION CHARACTERISTICS IN A TELECOMMUNICATIONS SYSTEM

摘要

The invention discloses an apparatus (100) in a wireless telecommunications system, comprising at least a first antenna (110) of a first polarization and a second antenna (120) of a second polarization. The apparatus (100) additionally comprises a receiver (130) and a transmitter (140), and is intended for communication with at least one other device in the wireless telecommunications system. The apparatus (100) is equipped with means (150, 204) for estimating the polarization state of a signal which is received from the one other device, and the apparatus (100) additionally comprises means (160, 206) for adapting the polarization state of signals transmitted from the apparatus (100) to the one other device on the basis of said estimate of the received signal.
