ALEXANDRIA, Va., June 16 -- United States Patent no. 12,308,871, issued on May 20, was assigned to Rockwell Collins Inc. (Cedar Rapids, Iowa).
"Efficient cross-correlation with adaptive polar quantization" was invented by Carlos J. Chavez (Marion, Iowa).
According to the abstract* released by the U.S. Patent & Trademark Office: "A system and method for signal cross-correlation using adaptive polar quantization and polar multiplication is disclosed. The method includes receiving a first and second complex signal. The method includes computing a first quantized phase and a first quantized magnitude based on a first adaptive polar quantization of a sample of the first complex signal and computing a second quantized phase and a second quantiz...
