MUMBAI, India, July 24 -- Intellectual Property India has published a patent application (202418072358 A) filed by Telefonaktiebolaget Lm Ericsson Publ on September 25, 2024, for Split Gain Shape Vector Coding.
Inventors include Norvell, Erik; Toftgrd, Tomas; and Grancharov, Volodya.
The application for the patent was published on July 17, 2026, under issue no. 29/2026.
Abstract: The invention relates to an encoder and a decoder and methods therein for supporting split gain shape vector encoding and decoding. The method performed by an encoder, where the encoding of each vector segment is subjected to a constraint related to a maximum number of bits, BMAX, allowed for encoding a vector segment. The method comprises, determining an initial number,Np_init, of segments for a target vector x; and further determining an average number of bits per segment, BAVG, based on a vector bit budget and Np_init. The method further comprises determining a final number of segments to be used, for the vector x, in the gain shape vector encoding, based on energies of the Np_initsegments and a difference between B and BAVG. The performing of the method enables an efficient allocation of the bits of the bit budget over the target vector.
