Orthogonal Space
Time Codes, Decoding Data Transmissions Patents Awarded to
NJIT
Two new patents to
improve orthogonal space time codes
and decode data transmissions of
space time spreading were recently
awarded to NJIT Distinguished
Professor Yeheskel Bar-Ness
executive director of the Elisha
Yegal Bar-Ness Center for Wireless
Communications and Signal Processing
Research. Co-inventors with Bar-Ness
on both patents were NJIT alums Amir
Laufer and Kodzovi Acolatse.
"Method and
Apparatus for Improving Transmission
with Orthogonal Space Time Codes,"
(US Patent # 8.379.746) was awarded
Feb.19, 2013 to Bar-Ness and Laufer.
“Modern wireless communication
systems utilize multiple antennas
for transmitting and receiving the
data,” said Bar-Ness. “A
simple, yet powerful coding scheme
for such systems is orthogonal space
time coding. This invention
involves a novel method for the
transmission and the decoding of
such codes resulting in better
utilization of the channel, i.e.,
transmission with higher data rate
along with lower error rate.”
"Decoding Data
Transmitted Space-Time Spreading in
a Wireless Communication System
Implementation and Performance
Analysis of Space Time Spreading
DS-CDMA System,” (US Patent #
8.355426) was awarded Jan. 15, 2013
to Bar-Ness and Acolatse.
Bar-Ness, a
prominent expert in wireless
communications and signal
processing, has worked for four
decades to advance the field of
electrical and computer engineering.
Bar-Ness, who still directs the
Center for Wireless Communications
and Signal Processing Research, has
worked with industry, government and
other universities to improve many
aspects of wireless technology.
An especially
notable achievement of the Center is
the set of algorithms developed by
its researchers. The
algorithms have become industry
standards, used to facilitate
so-called code division multiple
access (CDMA), a widely-used digital
cell phone technology. Faculty
affiliated with the center--the
backbone of communications research
in the department of electrical and
computer engineering at NJIT for two
decades--have received funding for
projects from the National Science
Foundation, the US Army and Air
Force and companies that include
AT&T, ITT, InterDigital, Nokia,
Mitsubishi, Panasonic, Samsung and
Telcordia.
Both Laufer and
Acolatse received doctorates in
electrical engineering from the
Department of Electrical and
Computer Engineering at Newark
College of Engineering in 2011 and
2010, respectively. Laufer is
now a senior DSP Algorithms Engineer
for Intel Israel at its development
center in Jerusalem. Acolatse
is a patent examiner at the US
Patent and Trademark Office in
Washington, DC.
The Center was
established in 1985. Its main
areas of research are CDMA and
spread spectrum systems,
multi-carrier modulation,
ultra-wideband communications, MIMO
systems, space-time codes and
turbo-codes, information theory and
adaptive signal processing.
Center members are noted experts in
this field.
