ALEXANDRIA, Va., Oct. 28 -- United States Patent no. 12,449,508, issued on Oct. 21, was assigned to Aptiv Technologies AG (Schaffhausen, Switzerland).

"Spatial-block code division multiplexing (CDM) for multiple input multiple output (MIMO) waveforms" was invented by Zhengzheng Li (Agoura Hills, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Techniques and systems are described for Spatial-Block Code Division Multiplexing (CDM) for MIMO waveforms. A radar system includes multiple transmitters, receivers, and phase shifters. Electromagnetic (EM) signals are transmitted and received in a Spatial-Block CDM scheme. Each spatial block has multiple slots outnumbering the channels. In addition, each slot cor...
