Inventor(s) include Dr. Priti Subramanium; and Dr. Suresh Yarlagadda.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "Implementation of OFDM System Using FPGA ABSTRACT The invention presents an optimized implementation of an Orthogonal Frequency Division Multiplexing (OFDM) system using Field Programmable Gate Array (FPGA) technology for high-speed wireless communication. The proposed system leverages the parallel processing capabilities of FPGA to perform real-time signal processing functions, including modulation, inverse Fast Fourier Transform (IFFT), cyclic prefix insertion, channel estimation, Fast Fourier Transform (FFT), and demodulation. These critical operations are executed simultaneously, ensuring low-latency performance suitable for modern communication standards like 4G LTE and 5G NR. The system's modular architecture enables easy adaptation to various communication protocols, making it scalable for future wireless technologies. A key advantage of this design is its power efficiency, as FPGA-based systems consume significantly less power compared to software-based or ASIC implementations, while still maintaining high-speed data transmission. Additionally, the reconfigurable nature of FPGAs allows for rapid prototyping and customization based on specific system requirements. The invention's flexibility and performance make it a cost-effective solution for broadband wireless communications, digital video broadcasting, and high-speed data transmission systems. By optimizing resource utilization and reducing computation time, this FPGA-based OFDM system ensures efficient spectrum usage and reliable communication in a variety of applications."
