ALEXANDRIA, Va., Dec. 9 -- United States Patent no. 12,494,823, issued on Dec. 9, was assigned to Lenovo (Singapore) Pte. Ltd. (Singapore).
"Calculating an EVM of a transmitter" was invented by Colin D. Frank (Park Ridge, Ill.).
According to the abstract* released by the U.S. Patent & Trademark Office: "Apparatuses, methods, and systems are disclosed for calculating an EVM of a transmitter. One apparatus includes a processor and a receiver that receives a multiple-layer MIMO signal from a transmitter via a propagation channel. The processor measures the received multiple-layer MIMO signal using an unbiased linear MMSE MIMO equalizer and calculates an EVM of the transmitter, where the EVM for each transmission layer is calculated as 100 ti...
