Topic 1:  Link Budget Analysis in Satellite Downlink Segment

Abstract: Link budget analysis is an integral part of general link analysis in radio communications. The analysis primarily deals  with power budget at each segment of the link and is used to determine transmit power, pathloss, and received power in order to ensure sufficient reliability for communication channels. In satellite application, the downlink payload (power amplifiers, waveguides, antenna, etc) is required to provide sufficient transmit power to overcome pathloss  and pathloss variations. Both ‘Clear Sky’ and ‘Rain’ conditions , which  are location dependent (satellite position to longitude & latitude point on earth), are considered in pathloss and associated variations  and ITU recommendations are addressed. Furthermore, antenna pointing, thermal, and aging variation in satellite payloads and ground receivers are also discussed. (ITU: International Telecommunication Union)

Speaker Bio: CK Chen received his PhD from University of California, Davis, in 1989, specializing in statistical signal processing and spectral analysis. He worked for NASA’s SETI Project from early to mid 1990s in Mountain View (Ames Research Center), responsible for architecture and design of a real-time multi-channel spectrum analyzer. He then joined Radix Technology to work on AT&T Angel Project, applying smart-antenna technology to a last-mile local-loop system for telephony and subsequently on a packet data based system for broad wireless access through early 2000s. In 2004, he joined Intel Corporation and worked on WiMax CPE equipment (16a & 16d) and in 2007Purewave Networks on WiMax base-station system. Today, he is with SSL (Space System Loral), a satellite manufacturer in Palo Alto, and is responsible for communication payload design.

Topic 2:  Long Term Evloution for Wireless Cellular System

Abstract: The Long Term Evolution (LTE) of UMTS (Universal Mobile Telecommunications System) discussions started within the 3rd Generation Partnership Project (3GPP) in 2004.  LTE was the first cellular communication system optimized to support packet-switched data services which was made available in Release 8 of the 3GPP specification series.  It was further developed in LTE Release 9, and Release 10 to continue the evolution progression known as LTE-Advanced.  The LTE-Advanced satisfied the criteria set by the ITU-R for IMT-Advanced and was accepted by the ITU as an IMT-Advanced technology in October 2010. LTE Rel-11 (Completed at late 2012) and Rel-12 (expected to be completed by the end of 2014) further extended the performance and capability of LTE.  With focus on Physical layer radio access evolution, the presentation will provide an introduction of the LTE evolution through different releases as well as potential evolution of LTE in the future.

Speaker Bio: Jong-Kae (JK) Fwu is a Principal Engineer and Manager of the PHY and System Simulations (PSS) group in MCG Standards and Advanced Technology, with his main focus being on 3GPP LTE RAN1 (PHY) standardization. JK has more than 15 years of experience in the industry of wireless (LTE, WiMAX, WiFi, Wireless Indoor Location) and wire-line (X-DSL) communications.

As Intel’s 3GPP RAN1 prime standard delegate, JK is leading Intel’s 3GPP RAN1 standardization activities. Since joining Intel in 2000, JK has been a leader of Intel’s technology and wireless standards development and has more than 100 contributions to wireless standardization bodies such as 3GPP, IEEE 802.16, and WiMAX Forum. Prior to 3GPP/LTE, JK served as vice-chair of IEEE 802.16 Task Group m (TGm) as well as Adhoc and Study Group Chairs of WiMAX Forum and IEEE. He holds various patents on communication system designs.  Before joining Intel, JK worked on algorithm design and system engineering for wireless handset and base stations.  JK received his M.S. and Ph.D. degrees both in Electrical Engineering.
