MUMBAI, India, July 31 -- Intellectual Property India has published a patent application (202647088321 A) filed by Nokia Technologies Oy on July 20, 2026, for Signal Phase Transitions For Transmissions In Communication Networks.
Inventors include Renfors, Markku; Tervo, Oskari; Tiirola, Esa Tapani; and Valkama, Mikko.
The application for the patent was published on July 24, 2026, under issue no. 30/2026.
Abstract: According to an example aspect of the present disclosure, there is provided a method comprising generating, for a binary data sequence, a sequence of trellis-coded modulation symbols in a complex Quadrature Phase Shift Keying, QPSK, constellation by means of a trellis code, generating a Discrete Fourier Transform, DFT, - precoded, Orthogonal Frequency Division Multiplexing, OFDM signal based at least on the sequence of trellis- coded modulation symbols and performing a transmission based on the generated DFT- precoded OFDM signal, wherein phase transitions between two successive trellis-coded modulation symbols of the sequence are determined by the trellis code, and wherein an absolute difference between two phase transitions successively-determined by the trellis code is at most p/2.
