MUMBAI, India, Sept. 12 -- Intellectual Property India has published a patent application (202517081283 A) filed by Lenovo (BEIJING) Ltd., Beijing, on Aug. 27, for 'precoder design for mimo transmission using orbital angular momentum modes.'
Inventor(s) include Zhu, Chenxi; Liu, Bingchao; and Zhang, Yi.
The application for the patent was published on Sept. 12, under issue no. 37/2025.
According to the abstract released by the Intellectual Property India: "Methods and apparatuses for OAM precoder are disclosed. In one embodiment, an OAM transmitter comprises TX antennas; and a processor, wherein, the processor is configured to: transmit, via the TX antennas, at least two OAM modes including OAM mode (l, p) and OAM mode (-l, p), where l is a positive integer and p is a non-negative integer, each OAM mode transmits one layer of signal in each utilized polarization; and apply a precoding matrix to the transmission of at least (l, p) and (-l, p) to mitigate the cross interference between (l, p) and (-l, p)."
The patent application was internationally filed on Apr. 14, 2023, under International application No.PCT/CN2023/088397.
