    Abstract: 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.

    Abstract: A method for estimating a signal to interference and noise ratio of a communication link between a first node and a second node of a wireless communication network, the network comprising a number of further communication links between said first node and a number of further nodes. The method comprises, at the first node, providing first estimates of useful signal powers on all the links; providing second estimates of the signal powers on the link and on the further communication links on the basis of, jointly, the first estimate of the signal power on the link and the first estimates of the signal powers on the further links; estimating the signal to interference and noise ratio as a ratio between the second estimate of the signal power on the link and a power term comprising a sum of the second estimates of the signal powers on the further links.

    Abstract: A method for scheduling radio resource allocation among active flows within a wireless communication network. The method includes, at each working period of the scheduling method; for each active flow, checking presence of priority data to be transmitted within the current working period. Each active flow having priority data to be transmitted within the current working period is classified as a priority active flow. The remaining active flows are classified as non-priority active flows, the non-priority active flows having non-priority data that need not to be transmitted within the current working period. Radio resources are allocated among the priority active flows, and corresponding priority data are transmitted over the respective allocated resources. After completing priority data transmission, the radio resources are allocated among the non-priority active flows and corresponding non-priority data are transmitted over the respective allocated radio resources until the end of the current working period.
