Company is looking to
fill the position
of principal scientist
in the Baseband
Demodulator VLSI/Group.
Company is a fabless
semiconductor company
developing integrated
circuits (ICs) for the
developing
mobile television
market, specifically
addressing mobile audio
and video standards such
as DVB-H, ISDB-T, T-DMB,
and DAB.
The Company has
assembled a world-class
team of engineers with
expertise in radio
frequency (RF) systems
and circuit design,
phase locked loops (PLLs),
analog-to-digital
converters, digital
communication systems,
digital signal
processing, very large
scale integrated (VLSI)
circuits, low power
logic and circuit
design, and
system-on-a-chip (SOC)
design. The
Baseband Demodulator
VLSI/Systems Group
currently consists of 15
engineers,
with over half of these
engineers holding Ph.D.
degrees in engineering
disciplines related to
IC design.
The job description for
this open position has
two components.
The first component is
to
research and specify
advanced communications
systems for mobile
receivers. This
requires an
understanding of
demodulation algorithms
for orthogonal frequency
division multiplexing (OFDM)
signals, expertise in
advanced digital signal
processing (DSP)
and
digital communication
principles
such as digital
filtering,
digital
timing and carrier
recovery,
channel estimation, and
equalization.
Deep understanding of
forward error correction
(FEC)
techniques
is required, including
Galois field theory,
Reed-Solomon codes,
convolutional codes,
Turbo codes,
and combinations of
these such as
concatenated codes and
product codes.
Experience in efficient
implementation of FEC
decoders such as Viterbi,
Reed Solomon, and Turbo
decoders is required.
The second component is
to
research and develop
an
ASIC implementation
of the specified system
which is
energy efficient
and has a
small silicon footprint.
Energy efficiency is
required due to the
battery powered nature
of mobile devices, and
an energy efficient
implementation requires
the use of state of the
art design techniques
such as voltage scaling,
power islands, and clock
gating, and development
of VLSI architectures
designed to reduce
dynamic switching
power. A small silicon
footprint is required
due to the cost
sensitivity and small
form factor of mobile
devices, and this
requires area efficient
VLSI architectures along
with a solid
understanding of the
system so the
proper balance can be
struck between silicon
area and system
performance.
Based on the breadth and
depth of expertise
required for this
position, it is expected
that the successful
candidate will have a
Ph.D. in Electrical
Engineering
or a related discipline
along with
at least 5 years of
relevant experience.
