<p>A radio communications receiver (4), comprising means (6, 8, 10) for detecting radio signals representative of data and for generating, from the detected radio signals digital signal samples, a plurality of the signal samples being representative of a datum of the data. The receiver (4) further comprises at least one data detector (14) having a scaling filter (22) coupled to the means (6, 8, 10) for detecting the radio signals and arranged to scale the plurality of signal samples ri with a plurality of scaling coefficients gi and to combine the scaled plurality of signal samples into a composite signal sample zi, from which the datum is re-generated. The data detector may further include a data detector controller (36) coupled to the scaling filter (22) which operates to adapt the scaling coefficients gi consequent upon an error signal ei derived from the composite signal. The receiver may be arranged to detect CDMA signals, and in particular TD-CDMA signals. The receiver can be developed in a modular fashion by providing a separate data detector for each of the transmitted signals to be detected.</p> |
