摘要： A received signal of interest is processed by determining timing of interference spikes in the received signal of interest. Receivers can determine when certain types of interference spikes are expected to occur, e.g., based on when different users are scheduled to transmit data during an overlapping portion of the same transmission time interval. The interference timing information is used by the receiver to soft scale signal values recovered from the received signal of interest that coincide with the interference spikes separately from remaining ones of the signal values. This way, fast changing interference power can be accurately tracked during periods of known interference spikes while also accurately tracking slower changing interference power during other periods.

摘要： Methods and apparatus are disclosed for suppressing both own-cell and other-cell interference in the processing of multiple signals of interest in a received composite signal. In an exemplary embodiment of the methods disclosed herein, combining weights for each of a first plurality of signals of interest in a composite information signal are computed, based on first shared signal correlation data computed from the composite information signal. A reduced-interference composite signal is calculated from the composite information signal, using, for instance, subtractive interference cancellation or interference projection techniques. Combining weights for processing each of a second plurality of signals of interest are computed as a function of second shared signal correlation data corresponding to the reduced-interference composite signal. Corresponding apparatus, including G-Rake and chip equalizer embodiments are also disclosed.
