Overview:

This course provides a comprehensive coverage of UMTS and its emerging advanced features facilitated with the latest standard releases (R5/R6). An in-depth coverage of the following topics should be expected:

1. The architecture of the physical (PHY), Medium Access Control (MAC) and Radio Resource Control layers of the UMTS protocol stack that enable high speed packet access mobility services. 

2. PHY-layer algorithms in Base Station (Node-B) and User Equipment (UE) transceivers such as synchronization, equalization for HS-PDSCH, channel estimation, SIR estimation, code tracking, Doppler spread and frequency offset compensation.

3. MAC layer features such as Adaptive Bit-Interleaved Coded Modulation (BICM), Incremental Redundancy (IR) based Hybrid-ARQ. Node-B MAC layer algorithms such as optimal rate control where fast allocation of resources to multiple simultaneous transmissions in the downlink and in the uplink high speed channels, UE and Hybrid-ARQ process scheduling.

4. Modeling of the mobile radio channel for accurate performance characterization of multiple antenna techniques.

5. System level performance using the Instantaneous Value Interface (IVI) simulation methodology.

Lecturer Biography:

Pantelis Monogioudis received his Ph.D. and M.Sc. from the University of Surrey, England, UK, in 1994 and 1991 respectively. He received his BEng (highest honors) from the Technological Educational Institute (TEI) of Athens in 1989. From 1991 to 1993 he was a Research Scientist in Philips Research Laboratories (PRL), Redhill, England UK. During this time he participated in the EU-funded CODIT project that lead to the prototyping of Europe’s first UMTS (W-CDMA) prototype access network and mobile terminal. Between 1994 and 1996 he was with Intracom SA, Athens, Greece, where he worked on DECT Radio Local Loop (RLL) and EU funded projects, under the ACTS R \& D framework, such as RAINBOW and EXODUS. During this time he was also part-time employed in ETSI, Sophia Antipolis, France as Technical Expert in Project Team No. 10 that standardized DECT. In 1997 he joined Lucent Technologies where he initially worked in the project that delivered W-CDMA prototype equipment to NTT DoCoMo, and also on various generations of W-CDMA ASICs that are currently used in Lucent’s Node-B equipment. In 2000 he was promoted to Distinguished Member of Technical Staff and transferred to Whippany NJ, where he engaged in R\&D projects related to HSDPA/HSUPA and Intelligent Antenna technologies. Since Sept 2004 he is with Invento Networks Inc. where he leads the wireless algorithms team in developing advanced WiMAX OFDM(A) base station channel elements. Dr Monogioudis has an extensive publication record and has co-authored 27 patent applications (6 granted) in CDMA communication systems and smart antenna techniques.
