Abstract:
Digital Radio
Processing is
an emerging field in wireless communications.
The
distinguishing
feature of
this field is the use of signal processing
techniques
to
alleviate the
analog design challenges in low-cost digital
CMOS
processes. In
this
presentation, some of these ideas are applied to
receiver
design to
reduce its
complexity. The principle of direct rf
sampling
and
manipulation of
charge to produce desired filtering will be
presented.
Handling analog
impairments in the receive chain through by
applying
signal
processing
techniques will also be visited. Some
measurement
results will be
shown to demonstrate the power and potential of these
schemes.
Biography:
Khurram Muhammad
received the
B.Sc. degree from the University of
Engineering &
Technology,
Lahore, Pakistan in
1990, the M.Eng.Sc.
degree from the University of Melbourne, Parkville, Victoria, Australia
in
1993 and the Ph.D. degree from Purdue University, West Lafayette,
IN in
1999, all in electrical engineering.
From 1990 to 1991
and 1993 to
1994, he worked in the Research and
Development
section of the
Carrier Telephone Industries, Islamabad,
Pakistan,
where he developed board level designs for rural and urban
Telecommunication.
He also
worked for the Ghulam Ishaq Khan Institute
of Engineering
Science and
Technology from 1994 to 1995 as a Research
Associate in the
Department
of Electronic Engineering. In 1995, he
developed fast
simulation
techniques for DS/CDMA systems in multipath
fading environment
at the
Hong Kong University of Science and
Technology, Kowloon, Hong Kong.
Since 1999, he has
been
working at Texas Instruments, Dallas, TX,
earlier in the advance read channel development group then in
communications
and
control
products and currently in the wireless terminal business
unit where
he leads system architecture and receiver
development and
serves as the
manager of the DRP system design
group. He also
serves on the
technical program committees of several IEEE conferences.
His main
research interests include CMOS mixed signal VLSI
design, advance
CAD techniques exploring digital design tradeoffs at
circuit and system levels, low-complexity
and low-power design.
