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.
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.
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.
