US Patent Issued to Arbe Robotics on Sept. 23 for "Efficient direction of arrival estimation using low rank approximation" (Israeli Inventor)

ALEXANDRIA, Va., Sept. 23 -- United States Patent no. 12,422,538, issued on Sept. 23, was assigned to Arbe Robotics Ltd. (Israel).

"Efficient direction of arrival estimation using low rank approximation" was invented by Noam Arkind (Givatayim, Israel).

According to the abstract* released by the U.S. Patent & Trademark Office: "A novel and useful system and method for direction of arrival (DOA) estimation having a complexity of order O(N log N), which allows a DOA dependent calibration. In one embodiment, the architecture comprises several fast Fourier transform (FFT) machines operating in parallel with coefficient multiplications before and after the FFT operations. These pre and post coefficients are computed using an optimal low rank ap...
