US Patent Issued on March 11 for "Phase-noise mitigation by embedded phase-tracking signals in 5G/6G" (California Inventors)

ALEXANDRIA, Va., March 12 -- United States Patent no. 12,250,106, issued on March 11.

"Phase-noise mitigation by embedded phase-tracking signals in 5G/6G" was invented by David E. Newman (Poway, Calif.) and R. Kemp Massengill (Palos Verdes, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "Access to FR2 (high frequency bands) is essential for anticipated high-demand networking in 5G-Advanced and 6G systems. Unfortunately, phase noise is an unavoidable barrier, greatly limiting message reliability. Therefore, a low-cost solution is provided in which the transmitter (either base station or user device) transmits a special phase-tracking reference signal consisting of zero amplitude in one branch, and a pre...
