INVESTIGATION OF DUAL-MODE AND DUAL-LINK UE SYSTEM PERFORMANCE UNDER ITS LOCAL INTERFERENCE EXISTENCE

摘要

To effectively investigate the dual-mode and dual-link (DM-DL) user equipment (UE) local interference,and so as to further improve its communication performance,a DM-DL UE system is firstly modeled,together with its interference analyzed and performance evaluated.Due to the sharp deterioration of the receiving sensitivity of the DM-DL UE under the local interference,then a high isolation double-band handset antenna is developed in details by using both the simulations and the measurements.At last,based on this antenna,a RF isolation solution is presented with its isolation effect verified.Final simulated results show that the DM-DL UE can work normally with the RF isolation.
