Acorn Technologies Announces HellaPHY IP Core for Industry-Leading Performance in 4G Wireless Networks

Acorn Offers Exceptional Spectral Gain More Economically

CHICAGO--October 19, 2010--Acorn Technologies (www.acorntech.com), an Intellectual Property (IP) development and commercialization company, today announced the launch of HellaPHY™, a chip-level IP core solution for OFDM-based 4G wireless networks that offers more than 60 percent gain in spectral efficiency. With the resulting increase in capacity and bandwidth efficiency, mobile operators can deliver higher data rates and wider coverage to end-users, greatly improving the business case for operators deploying LTE or WiMAX networks.

HellaPHY works by increasing overall receiver performance, offering capacity improvements under challenging mobile channel conditions--including co-channel interference, inter-carrier interference, multi-path interference and thermal noise. Compared to other technologies, HellaPHY provides some of the highest spectral gain per dollar while retaining critically low implementation complexity. The HellaPHY implementation can be easily integrated into a 4G chipset solution with minimal impact, yet provides great technical performance improvement.

In addition, HellaPHY can work with single antenna or as an improvement to multiple antenna (MIMO) receivers. When embedded in handsets or base stations, the technology greatly reduces network total cost of ownership (TCO). Service providers can deploy fewer base stations and still deliver a better user experience.

“Acorn’s approach to equalization and channel estimation differs greatly from what is available in OFDM systems today,” said Steve Caliguri, vice president of Telecoms for Acorn Technologies. “We have taken years of experience in signal processing and applied it in a very unique way. The mathematical techniques we employ allow for a greatly simplified implementation that otherwise could not be possible in consumer devices.”

“With the launch of HellaPHY for 4G wireless networks, Acorn Technologies is executing its mission to bring game changing solutions to large technology-based markets,” said Tom Horgan, CEO, Acorn Technologies. “The company has several important technology solutions that are being launched over the next 12 months in the semiconductor and telecom markets.”
