MUMBAI, India, Aug. 12 -- Intellectual Property India has published a patent application (202647091953 A) filed by Qualcomm Incorporated on July 29, 2026, for Mimo Demodulation Of Probabilistically-Shaped Qam Using Lattice Basis Reduction.
Inventors include Taherzadeh Boroujeni, Mahmoud; Yang, Wei; and Li, Qiaoyu.
The application for the patent was published on August 07, 2026, under issue no. 32/2026.
Abstract: This disclosure provides systems, methods and apparatuses for demodulating multiple-input multiple-output (MIMO) transmissions with N layers with probabilistic shaping according to a distribution such as the Maxwell-Boltzmann distribution. A demodulator at a receiving device projects a received 4N-dimensional point to a 2N- dimensional subspace spanned by probabilistic shaping demod-equivalent receive constellation points to obtain a projected received point. The demodulator performs lattice basis reduction for a 2N-dimensional lattice to obtain a reduced basis lattice. The demodulator obtains a nearest point of the reduced basis lattice to the projected received point using linear demodulation with the reduced basis lattice.
