Dr. S. A. Khan Dr. Khan’s areas of specialization are Digital Signal Processing,
Digital Design and Communication System. He has authored or co-authored more 65
publications in journals and conferences.
Dr. Khan has Ph.D. in Electrical and Computer Engineering from Georgia Institute
of Technology; Atlanta, GA. Analog Devices funded his Ph.D. on a project for MIT
Lincoln Lab, which involved 64 SHARC DSPs based Mesh for parallel processing application.
He obtained his B.Sc. in Electrical Engineering from UET, Lahore
He has 12+ years industrial experience in companies like Scientific Atlanta, Picture
Tel, and Cisco Systems. Mostly he worked on multi-DSP-based systems. As head of
R&D group at Communications Enabling Technologies, he headed the team that executed
a pioneering work of System on Chip (SoC) design. The team designed the world highest
density media processor for carrier class voice processing system. The SoC can handle
2000 calls of G.711 or 624 calls of G.729a with line echo cancellation, voice activity
detection, and comfort noise generation. SoC has 40 DSPs with embedded silicon RTOS
taking care of the scheduling of different voice channels on these DSPs. A system
based on this chip is installed in PTCL 17-enquiry exchange in Peshawar, Pakistan.
He is one of the five recipients of National Education Award 2001 in the category
of "Outstanding Services to Science and Technology".
