MUMBAI, India, Sept. 14 -- Intellectual Property India has published a patent application (202611087118 A) filed by Noida Institute Of Engineering And Technology Niet on July 16, 2026, for System And Method For Secure Wireless Precoding Exploiting Power Amplifier Distortion.
Inventors include Nitu Rao; and Deepti Mehta.
The application for the patent was published on September 11, 2026, under issue no. 37/2026.
Abstract: The present invention discloses an adaptive distortion-aware secure precoding system (100) and method for multi-antenna base stations comprising a transmit antenna array (170) with per-antenna power amplifiers (172) and a signal processing unit (180) with analog-to-digital and digital-to-analog converters. The system exploits power amplifier nonlinear distortion to enhance physical layer security through a channel estimation module (110), a power amplifier characterization unit (120) employing polynomial regression with adaptive regularization, a graph neural network secure precoding engine (130) on a bipartite antenna-user graph, a distortion steering controller (140), a PA-aware training pipeline (150) optimizing precoding weights using differentiable secrecy rate objectives from signal decomposition, and a security assessment module (160). The system operates without eavesdropper channel information or dedicated artificial noise, achieving enhanced secrecy rates under power amplifier saturation with real-time inference latency.
