MUMBAI, India, Sept. 22 -- Intellectual Property India has published a patent application (202541022940 A) filed by Tejas Networks Limited on March 13, 2025, for Power-Based Signal Modulation For Consistent Performance And Noise Resistance.
Inventor includes Vinod Kumar M.
The application for the patent was published on September 18, 2026, under issue no. 38/2026.
Abstract: This invention introduces a modulation and demodulation method that ensures uniformly spaced power levels by adopting non-uniformly spaced voltage levels, leading to improved noise immunity and energy efficiency. By maintaining a constant power difference between adjacent signal levels, the system ensures uniform noise performance and enhanced coding efficiency. This approach is applicable to M-PAM and M-QAM systems, optimizing power distribution across sub-carriers in multi- carrier communication systems like OFDM. The method enables efficient power utilization, reducing energy consumption while enhancing signal robustness. It supports integration with advanced encoding schemes such as block, convolutional, turbo, and LDPC encoders. Designed for wireless communication systems, base stations, and energy-efficient IoT networks, this invention provides a scalable and practical solution for next-generation high-speed, low-power data transmission, ensuring optimal performance across different communication environments.
