Abstract: Embodiments of the present disclosure relate to methods, apparatuses and computer program products for signal detection in a wireless communication system. A method implemented at a receiver device includes obtaining a set of received signals; determining a channel on which the set of received signals are transported; and detecting a set of transmitted signals from the set of received signals in an iterative manner based on the determined channel, a modulation mode for the set of transmitted signals, and the set of received signals, by using a gradient descent (GD) algorithm. Embodiments of the present disclosure may reduce computation complexity required in signal detection and/or improve detection performance.

Abstract: Embodiments of the present disclosure relate to methods, apparatuses and computer program products for signal detection in a wireless communication system. A method implemented at a receiver device includes obtaining a set of received signals; determining a channel matrix via which the set of received signals have been transported; and detecting the set of received signals in a staged manner, wherein in a stage, the method includes detecting the set of received signals, based on the channel matrix and a detection algorithm for the stage; fixing one or more of detected symbols output from the detecting algorithm for the stage; and updating the channel matrix and the set of received signals for usage by a next stage, based on the one or more of the detected symbols that are fixed in the stage.
