摘要： A method, receiver and program for processing a signal received using a wireless communication channel by a receiver in a wireless cellular network. The method comprises: receiving signal samples of a signal to be processed from a serving cell; identifying a set of dominant interfering cells generating an interfering signal above a level; using the number of cells in the set to select an interference scenario; and using the selected interference scenario and at least one parameter related to the serving cell and the interfering cells to select a processing function for processing the signal.

摘要： The present invention provides a method of estimating a frequency offset. The method comprises receiving a wireless signal timed according to a first frequency; generating a local signal timed according to a second frequency; and performing a plurality of synchronization searches, each search comprising obtaining a set of correlation results indicative of a correlation between the wireless signal and the local signal at different timing offsets of the wireless signal relative to the local signal. The method the no comprises finding a series of results, with a result from each of a plurality of the synchronization searches, for which the difference in; timing offset between results from adjacent searches in the series is within a maximum specified value. A frequency off set between the first and second frequencies can be determined from the series.

摘要： An apparatus, method and program for processing a signal received over a wireless channel. The apparatus comprises: a channel searcher configured to determine a profile of the channel in the form of energy values for a plurality of rays at respective channel positions, and an equalizer for equalizing the signal based on a variable window of the equalizer. The channel searcher is configured to estimate dispersion of the channel by determining a measure of variance of ray distance from a reference position within the channel profile weighted by ray energy. The equalizer is coupled to the channel searcher and arranged to adapt the window in dependence on the measure of energy-weighted ray distance variance.
