Featured Researcher
Dr. Sharad Sambhwani
Dr. Sharad Sambhwani is a Senior Staff Engineer/Manager in the Corporate Research and Development department at Qualcomm. His research interests are in the areas of signal processing, detection theory, estimation theory, and advanced receiver algorithms for wireless systems. He is currently a physical layer systems engineering lead contributing towards multiple enhancements to 3G W-CDMA /HSPA technologies. In particular, he has worked on advanced NodeB receiver algorithms such as uplink interference cancellation, as well as many of the 3GPP Release 7 and 8 HSPA+ features. He also represents Qualcomm as the lead standards delegate for the 3GPP RAN1 HSPA meetings.
Dr. Sambhwani joined Qualcomm in June 2004, first working on the system study of 3GPP TD-CDMA. He has since been involved in a project primarily focused on the evolution and enhancement of 3GPP W-CDMA/HSPA technology.
Dr. Sambhwani is a Member of the IEEE and has been granted 35 patents in the areas of wireless communications and signal processing.
Dr. Sambhwani received his received the M.S and PhD degrees (EE) in 1992 and 1997 respectively from Polytechnic University, Brooklyn, NY. He began his career in 1996 at the Bell Laboratories division, Lucent Technologies where he worked on the system design of robust CAS tone detection in the presence of speech as well as on the base-band system design and development of an IS-95/ANSI-08 CDMA handset. From 1998 to 2001, he worked at National Semiconductor, Inc (formerly Algorex, Inc) where he helped develop the Simulink CDMA Blockset Library (a Mathworks product) as well as contributed towards the system design and performance evaluation of both cdma2000 1x and W-CDMA base-band chipsets. He also attended 3GPP RAN1 Standards meetings from 1999 to 2001. In 2000, he was promoted to Director of Systems Engineering, responsible for a team that contributed towards a prototype to help evaluate the performance of advanced CDMA algorithms. From 2001 to 2004, he worked at Quicksilver Technology, San Diego, a startup focused on reconfigurable computing, where he contributed towards the system design and implementation of multiple physical layers such as W-CDMA and 802.11a PHY/MAC layer on a common adaptive computing machine.
