Alexander Haimovich wants to improve consumer wireless services during the next three years, despite predictions of worsening services. That’s why Haimovich, an electrical and computer engineering professor at New Jersey Institute of Technology (NJIT), will lead a research team to prevent a downturn in services. The plan is to tighten cooperation of processing signals between wireless network base stations, such as cellular networks.
“The rapid expansion of cellular phones and the Internet emboldens consumers to demand mobile access to a wide range of services from information to entertainment,” Haimovich said. “Well, with this kind of accelerated demand, service for virtually all users portends to only get worse.”
Base stations, which take in signals, will become greater gateways to the Internet, in addition to their traditional role serving as a conduit for voice messages. Base stations currently operate independent of, or with limited collaboration from, other base stations. “Our research will answer whether tighter cooperation in processing signals between base stations can enhance performance,” said Haimovich.
Wireless services impacted by an upsurge in use will include cell phones and MP3 players. Affected technologies will include cellular, WiFi and the new WiMax technology. A three-year $360,000 National Science Foundation grant supports the work.
The research team, based at the Center for Wireless Communication and Signal Processing Research at NJIT, is a joint effort with Princeton University. It continues a tradition of cooperation with other New Jersey research universities regarding research on wireless topics. Yeheskel Bar-Ness, PhD, distinguished professor in the department of electrical and computer engineering, at NJIT is director of the center.
Haimovich's other research interests include the development of a new type of radar sensor. “This radar would use multiple transmitters and receivers to achieve improved resolution of target locations,” he said. The U.S. Air Force Office of Scientific Research funds this research. Haimovich has been involved developing surveillance techniques for the U.S. Army. And, he has focused on creating new ultra-wideband signals for communications. Such signals would allow consumers to receive improved wireless entertainment in their homes. “Once we have the right broadband width, we're going to use one wireless box for telephone, television and internet services,” he said.
Haimovich has worked at NJIT since 1992, and recently served as director of the New Jersey Center of Wireless Communications Telecommunications. In 2003, Haimovich chaired the Globecom symposium, which delves into cutting-edge communication theory. The International Electric and Electrical Engineers, Inc. (IEEE) has sponsored the event since 1957. Haimovich is an associate editor for IEEE “Communications Letters” and was a guest editor for a special issue about turbo coding for the “Journal of Applied Signal Processing,” published by the European Association for Signal and Image Processing (EURASIP).
Haimovich received his doctorate in systems from the University of Pennsylvania, his master’s degree from Drexel University and his bachelor’s degree from the Technion, Israel, both in electrical engineering.
