US Patent Issued to Wi-LAN on June 24 for "Mitigation of transmission errors of quantized channel state information feedback in multi antenna systems" (Canadian Inventors)

ALEXANDRIA, Va., June 25 -- United States Patent no. 12,341,579, issued on June 24, was assigned to Wi-LAN Inc. (Ottawa).

"Mitigation of transmission errors of quantized channel state information feedback in multi antenna systems" was invented by Bartosz Mielczarek (Edmonton, Canada) and Witold A. Krzymien (Edmonton, Canada).

According to the abstract* released by the U.S. Patent & Trademark Office: "Methods are disclosed for improving communications on feedback transmission channels, in which there is a possibility of bit errors. The basic solutions to counter those errors are: proper design of the CSI vector quantizer indexing (i.e., the bit representation of centroid indices) in order to minimize impact of index errors, use of error de...
