Latest Patents

One of Nikhil Gulati's latest patents is a method for selecting the state of a reconfigurable antenna in a communication system via machine learning. This method employs an online learning algorithm based on the theory of multi-armed bandit to optimize antenna state selection. The technique utilizes the Post-Processing Signal-to-Noise Ratio (PPSNR) as a reward metric, aiming to maximize long-term average rewards over time. The performance of this learning-based selection technique has been empirically evaluated using wireless channel data collected in an indoor environment with a 2×2 MIMO OFDM system. The results demonstrate significant performance improvements in terms of average PPSNR and regret compared to conventional heuristic policies.

Another significant patent involves reconfigurable antennas for performance enhancement of interference networks employing interference alignment. This innovation utilizes reconfigurable antenna-based pattern diversity to realize an optimal channel, maximizing the distance between two subspaces and thereby increasing the sum-rate. The benefits of pattern reconfigurability have been quantified using real-world channels in a MIMO-OFDM interference network, achieving an additional 47% gain in choral distance and a 45% gain in sum capacity. This advancement also improves the performance of interference alignment in low SNR regimes.
