Abstract :
This paper presents an adaptive impedance control of antennas on user equipment (UE) for a Long Term Evolution (LTE) system that supports MIMO reception in downlink and single antenna transmission in uplink. The proposed control method balances the performances of both links, duplexing with a frequency division duplex (FDD), without additional information from eNode B (eNB). In addition, computer simulations verify the effectiveness of the proposed method in the usage environment, where a user holds the UE under multipath propagation channels.
