UAE researcher at NYU gets patents for breakthrough inventions in BlueTooth

Dr Ahmad Bazzi, an inventor and researcher at New York University Abu Dhabi (NYUAD), has been granted a patent from the US Patent and Trademark Office (USPTO) for his breakthrough inventions in the field of quantum technology.

“US patent number 11,496,343 which was implemented back in my days working in industry with the intention of achieving better bluetooth data rates in real time! It was fun!” Dr Ahmad Bazzi (main picture), a researcher of electrical and wireless engineering, posted on his LinkedIn profile.

The patent, titled Method and related decoder for decoding rf signal carrying sequence of symbol modulated by cpm, with Dr Lisa Meilhac listed as co-inventor, was designed for decoding symbols encoded using the Continuous Phase Modulation (CPM) scheme.

More precisely, the invention is dedicated for certain Bluetooth standards, with a preference for Bluetooth BR (Basic Rate) and BLE (Bluetooth Low Energy).

The methods developed within the scope of this patent are aimed at enhancing the decoding process, particularly in the context of Bluetooth communication utilizing these specific standards.

The patent holds tremendous promise to revolutionize several industries, such as audio, health, internet of things (IoT), and related sectors and can be further leveraged for future communication schemes, including but not limited to ZigBee.

The patent brings several noteworthy advantages to wireless communication. CPM, known for its power and spectral efficiency, finds a simplified demodulation process through the method’s use of a Limiter-Discriminator Integrator (LDI) receiver, ensuring low complexity.

The innovative approach of this decoding method yields a significant performance gain, exceeding 4 dB when compared to the LDI demodulator. Crucially, it achieves this improvement while maintaining linear-scale complexity per received symbol, demonstrating efficiency and practicality.

Addressing the complexities associated with optimal receivers, especially in the presence of impairments like frequency offset, the method strikes a balance by offering a decoding solution that is both effective and operationally feasible.

Specifically designed for Bluetooth BR and BLE modulations, it adapts to the unique characteristics of these standards, providing a tailored and optimized decoding process for enhanced communication performance.

Dr Ahmad Bazzi also points out exclusively to our website, Robotics & Automation News, the flaws in future bluetooth standards and the need to address security and privacy concerns in bluetooth standards, especially in bluetooth <5.2.

Put in simple words, attackers can figure out the same key used in different bluetooth sessions, which also means that when attackers exploit these weaknesses, they can take over one session and use it to pretend to be devices or disrupt communication between connected devices.

It’s like someone finding a weak link in the security chain and exploiting it to control or mess with Bluetooth connections.
