This technology provides an innovative method to effectively suppress close-in and reciprocal mixing phase noise in radio frequency signals, enhancing signal clarity in communication systems without the need for training data or side information.
Background :
Phase noise in radio transmitters and receivers significantly degrades signal quality, especially in advanced communication systems like 4G, 5G, and millimeter-wave applications. Traditional methods to mitigate phase noise often rely on complex training sequences or additional side information, thereby increasing system complexity and reducing efficiency. Addressing this problem, this invention introduces a novel approach to reduce phase noise distortion without requiring these burdensome resources.
Technology Overview :
This technology centers on a unique mixing method that compensates for phase noise by leveraging oscillators generating scaled phase noise tones combined with multiple mixers operating at distinct tone frequencies. This design creates a receiver architecture optimized for down-conversion that inherently suppresses both close-in phase noise and reciprocal mixing noise. By carefully structuring the mixing stages and tone frequencies, the approach minimizes phase noise interference even in challenging signal environments. Importantly, it achieves this suppression without necessitating prior training or side information, simplifying implementation. This method is particularly valuable for modern communication systems that demand high-fidelity signal processing, such as 4G/5G wireless networks and millimeter-wave technologies. It enhances the reliability and performance of radios by reducing phase noise-induced distortions, thereby improving data integrity and communication quality. The novel architecture ensures compatibility with existing infrastructures while offering superior noise compensation capabilities.
Advantages :
• Effective suppression of close-in and reciprocal mixing phase noise, enhancing signal quality.
• Eliminates the need for training sequences or side information, reducing system complexity.
• Suitable for integration with advanced wireless communication technologies including 4G, 5G, and millimeter-wave systems.
• Improves the overall reliability and performance of radio receivers and transmitters.
• Maintains compatibility with existing signal processing architectures without requiring significant modifications.
Applications :
• 4G and 5G communication receivers and transmitters requiring enhanced phase noise management.
• Millimeter-wave communication systems where phase noise severely impacts performance.
• Ranging and radar systems that depend on precise signal clarity and minimal noise interference.
• Wireless communication infrastructure aiming to improve data integrity and reduce signal distortion.
• Any radio frequency system where phase noise poses a challenge to achieving high-quality signal reception and transmission.

About the State University of New York
The State University of New York is the largest comprehensive system of higher education in the United States, and more than 95 percent of all New Yorkers live within 30 miles of any one of SUNY’s 64 colleges and universities. Across the system, SUNY has four academic health centers, five hospitals, four medical schools, two dental schools, a law school, the country’s oldest school of maritime, the state's only college of optometry, 12 Educational Opportunity Centers, over 30 ATTAIN digital literacy labs, and manages one US Department of Energy National Laboratory. In total, SUNY serves about 1.7 million students across its portfolio of credit- and non-credit-bearing courses and programs, continuing education, and community outreach programs. SUNY oversees nearly a quarter of academic research in New York. Research expenditures system-wide are nearly $1.5 billion in fiscal year 2025, including significant contributions from students and faculty. There are more than three million SUNY alumni worldwide, and annually one in three New Yorkers who earn a college degree is a SUNY alum.
