NJIT New Patent Awards: Orthogonal Space Time Codes, Decoding Data Transmissions

NJIT Distinguished Professor Yeheskel Bar-Ness

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 U.S. 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.  To learn more about the center, contact Angela Retino (973) 596-8474 or aretino@njit.edu.

One of the nation’s leading public technological universities, New Jersey Institute of Technology (NJIT) is a top-tier research university that prepares students to become leaders in the technology-dependent economy of the 21st century. NJIT’s multidisciplinary curriculum and computing-intensive approach to education provide technological proficiency, business acumen and leadership skills. With an enrollment of 11,400 graduate and undergraduate students, NJIT offers small-campus intimacy with the resources of a major public research university. NJIT is a global leader in such fields as solar research, nanotechnology, resilient design, tissue engineering and cybersecurity, in addition to others. NJIT ranks 5th among U.S. polytechnic universities in research expenditures, topping $121 million, and is among the top 1 percent of public colleges and universities in return on educational investment, according to PayScale.com. NJIT has a $1.74 billion annual economic impact on the State of New Jersey.
