    摘要: A radio receiver apparatus of a cellular network includes a channel estimator configured to calculate channel estimates on the basis of a common pilot channel. The apparatus further includes a weight calculation unit configured to calculate a weighting factor on the basis of a signal power of the common pilot channel and control data depending on a transmit signal power of a dedicated data channel. The control data is signaled by the cellular network to the radio receiver apparatus. The radio receiver apparatus further comprises a combiner that combines the signals from multiple cells by using the channel estimates and the weighting factor.

    摘要: Described devices and techniques provide noise whitening in a communication device. The noise whitening is performed by a noise whitening unit that receives signals on a first path associated with a first antenna and signals on a second path associated with a second antenna. The received signals may include radio signals and channel coefficient signals. The noise whitening unit may perform noise whitening of the received signals in consideration of a covariance of the interference and noise associated with the received radio signals.

    摘要: A receiver apparatus includes a first receiver having an input for receiving a first version of a signal received by a first receive antenna. The receiver apparatus further includes a second receiver having an input for receiving a second version of the same signal received by a second receive antenna. The first receiver includes a first constellation demapper for demapping constellation symbols generated in the first receiver into a first soft decision bitstream and the second receiver includes a second constellation demapper for demapping constellation symbols generated in the second receiver into a second soft decision bitstream. A combiner is configured to combine the first soft decision bitstream and the second soft decision bitstream to provide a combined soft decision bitstream.
