My current publication record consists of Ph.D., L.Sc. and Master's Thesis, two journal papers and 23 conference papers. The topics of the publications deal with Wideband Code Division Multiple Access (WCDMA), High Speed Packet Access (HSPA) evolution and Long Term Evolution (LTE) network performance. Special interest in those studies have been paid on Multimedia Broadcast Multicast Service (MBMS) and Voice over IP (VoIP). The list of publications is shown below.
