ALEXANDRIA, Va., June 12 -- United States Patent no. 12,301,392, issued on May 13.
"Multi-phase vector synthesis demodulation method and apparatus" was invented by Chun Soo Park (Seoul, South Korea).
According to the abstract* released by the U.S. Patent & Trademark Office: "An N-phase vector synthesis demodulator employing N number of mixers is presented. The received signal is mixed with locally generated N number of phase-shifted carrier signals at the N mixers, the individual phases of which are successively and equally 360deg/N shifted. The final in-phase (I) and quadrature-phase (Q) signals are zero-force synthesized from the demodulated N-phase vector signals. Compared with the conventional I/Q demodulator that obtains the I and Q ...
