Acorn Technologies Introduces New Positioning IP Core for LTE Baseband Chipset Market

LA JOLLA, CA -- (Marketwired) -- Feb 03, 2016 -- Mobile World Congress - Acorn Technologies, Inc., a semiconductor and telecom research and development company, today launched the commercial availability of its new hellaPHY RSTD advanced signal processing IP core for LTE network based positioning and E911 indoor location accuracy standards. The hellaPHY™ RSTD IP core is targeted at the LTE baseband chipset market providers as the FCC mandates new 911 location reporting rules for wireless carriers.

hellaPHY RSTD, is an advanced signal processing algorithm that was developed to improve LTE wireless network indoor and outdoor location accuracy and offers extreme performance in an efficient low-power DSP implementation. The algorithm has been demonstrated to outperform advanced super-resolution algorithms at a fraction of the complexity. It is designed to be a drop-in replacement for existing Reference Signal Time Difference (RSTD) algorithms in User Equipment (UE) chipsets and can be customized for any unique DSP or interface requirements. The hellaPHY RSTD IP core is designed to support advanced LTE features contemplated by operators as well as for LTE Release 14 including PRS muting, CRS plus PRS transmit diversity, and fractional Ts reporting. The hellaPHY RSTD IP core is scalable and can support CAT-M through CAT-15.

"Our latest hellaPHY IP core is based upon our ground breaking work in developing channel estimation algorithms for LTE basebands and complies with the FCC's new rules on E911 indoor location accuracy and reporting, that will be mandated for wireless carriers in the very near future," said Steve Caliguri, vice president of Telecommunications for Acorn Technologies. "We expect to be shipping Acorn hellaPHY RSTD IP cores in certain LTE basebands later this year."

hellaPHY RSTD can also support indoor commercial applications and will help operators develop new features to enhance their user experience. The potential for new applications that can rely on a very low-cost and low power positioning using hellaPHY RSTD are enormous. In particular, with the emergence of IoT, where the cost and power of traditional GNSS based positioning solutions become more prohibitive, hellaPHY RSTD offers a low cost and accurate off-the-shelf solution.
