US 11,956,105 B2 · Soft-decision information generation for receiver

Abstract

Embodiments of the present disclosure relate to a method, an apparatus and a computer readable storage medium for generating soft-decision information for a receiver. In example embodiments, a method is provided. The method includes receiving, at a first device, a signal from a second device, the signal corresponding to a group of symbols transmitted from the second device; determining, by performing Lattice Reduction linear detection on the signal, a first group of estimated symbols for the group of symbols; determining, by performing iterative interference cancellation on the first group of estimated symbols, a second group of estimated symbols for the group of symbols; and generating, based on the second group of estimated symbols, soft-decision information about the group of symbols for use by a decoder at the first device. Embodiments of the present disclosure can improve the receiver performance with reduced complexity.

Dependent claims

An apparatus comprising:

at least one processor;
and
at least one non-transitory memory including computer program code;
the at least one non-transitory memory and the computer program code are configured to, with the at least one processor, cause the apparatus to:
receive a signal from a further apparatus, the signal corresponding to a group of symbols transmitted from the further apparatus;
determine, with performing lattice reduction linear detection on the signal,
a first group of estimated symbols for the group of symbols;
perform, based on a matrix characterizing a channel used to transmit the group of symbols from the further apparatus to the apparatus, the lattice reduction linear detection on the signal;
determine, with performing iterative interference cancellation on the first group of estimated symbols, a second group of estimated symbols for the group of symbols;
and
generate, based on the second group of estimated symbols, soft-decision information about the group of symbols for use with a decoder at the apparatus.
