Communications/ICWS Seminar --------------------------- An Overview of the LTE Wireless Broadband Communications Dr. Amitava Ghosh, Motorola Corporation 2-4 p.m. Friday, September 19, 2008 Room 301 Coordinated Science Laboratory ABSTRACT LTE is anticipated to be the market dominant standard for 4G wireless broadband communications by 2012. This seminar will consist of two one-hour parts, with a short break in the middle. Part I: LTE Multiple Antenna System: Performance and Antenna Structures: This presentation takes a look at different multiple antenna schemes for LTE downlink and uplink. The presentation also discusses various BTS antenna configurations and summarizes the performance of different multi-antenna schemes under various scenarios. Part II: LTE time division duplex (TDD) and comparison to LTE frequency division duplex (FDD): This presentation is focused on overview of LTE TDD design and highlights key differences with LTE FDD. Design challenges unique to TDD are presented together with adopted technical solutions. Finally, simulation results are provided to demonstrate typical TDD system performance with data applications. Short Biography of Amitava Ghosh Amitava joined Motorola in 1990 after receiving his Ph.D in Electrical Engineering from Southern Methodist University, Dallas. Since joining Motorola he worked on eight different wireless technologies starting from IS-95, cdma-2000, 1xEV-DV/1XTREME, 1xEV-DO, UMTS, HSPA, 802.16e/WiMAX/802.16m, Enhanced EDGE and 3GPP LTE. Recently, he led the effort from Motorola's side in defining 3GPP LTE physical layer standards from the concept phase to the adopted baseline. Amitava has 37 issued patents and numerous external and internal technical papers. He is the reviewer of IEEE communications society and book reviewer for a popular WiMAX book. Currently, he is Fellow of Technical Staff in Network Advance Technology, Motorola Home and Networks Mobility and works in the area of current and future air-interface technologies for 802.16m, 3GPP LTE and other broadband technologies. His research interests are in the area of digital communications, signal processing and wireless communications. He is a senior member of IEEE and associate member of Motorola Science Advisory Board.
