A receiver adapted to receive a modulated signal including useful and interfering signals and to detect information bits carried thereon. The modulated signal comprises signal components each one associated with a respective modulation subcarrier and including respective useful and interfering signal components. The receiver may include a first estimation unit providing a respective first useful signal component estimate indicative of the useful signal component for each signal component; a second estimation unit providing a respective second useful signal component estimate indicative of the useful signal component for each signal component; a channel estimation unit estimating, for each signal component, a first channel frequency response associated with the respective useful signal component and a second channel frequency response associated with the respective interfering signal component; and a control unit determining, for each signal component, an interference level experienced by that signal component according to respective first and second channel frequency responses.

Reconfigurable receiver for wireless communication networks

An iterative receiver receives a signal including useful and interfering signal components, and detects information carried thereon. The receiver includes at least one estimating unit receiving the signal and providing an estimate of each signal component, and at least two decoding and regenerating units, at each iteration, each decoding and regenerating unit decoding a respective one among the estimates and for regenerating the respective decoded estimate into a respective regenerated estimate. At each receiver iteration, the at least one estimating unit provides estimates based on regenerated estimates provided at a previous iteration. The receiver further includes a control unit determines activation or deactivation of each decoding and regenerating unit at each process step of a detection process dedicated to detection of the signal, and determines, for each process step, a respective number of allowed iterations for each decoding and regenerating unit whose activation has been determined for that process step.

Receiver for wireless communication networks

An iterative receiver is proposed for receiving in a cell a signal and for providing information carried on the signal by execution of at least one processing iteration. The receiver includes an estimate assembly for receiving the signal and providing, at each one of the processing iterations, a respective information estimate; a regeneration assembly for receiving, at each processing iteration, the information estimate provided by the estimate assembly at that iteration, and for providing a regenerated signal therefrom based on the information estimate and on attenuation of radio channels over which the signal has been transmitted; an interference estimate unit for providing, at each iteration, an interference estimate based on the signal and the regenerated signal, the estimate assembly providing, starting from a second processing iteration of the processing iterations, the information estimate based on the interference estimate; and an extraction unit for extracting the information from the information estimate.
