Abstract (en)
[origin: WO9901945A1] The invention relates to a signal detection method in a digital cellular network receiver. A combination of a desired useful signal and at least one interfering adjacent channel signal originating from a channel adjacent to a desired channel is received on the desired channel. In accordance with the invention channel estimates of the useful signal and at least one adjacent channel signal are jointly determined. The estimation is performed either using reference parts, for example a training sequence, known by the receiver or using symbol or bit decisions produced by decision feedback. Then the useful signal is detected utilizing the channel estimates of both the useful signal and the adjacent channel signal. The estimation can also be performed separately, in parallel or sequentially, in which case a reconstructed interfering signal is reduced from the useful signal before detection.
