摘要： Interference is cancelled from a baseband signal by synthesizing interference from estimated symbols in interfering subchannels. The estimated symbols are hard-coded, soft weighted, or zeroed, depending on the value of an estimated pre-processed signal-to-interference-and-noise ratio (SINR) in each subchannel in order to maximize a post-processed SINR. The estimated pre-processed SINR is obtained from averages of estimated symbol energies and estimated noise variances, or from related statistical procedures.

摘要： A wireless communication receiver improves signal impairment correlation estimation in MIMO/MISO systems by considering different transmit power allocations and different transmit antenna power distributions in its impairment correlation calculations. The receiver may be implemented in according to a variety of architectures, including, but not limited to, Successive Interference Cancellation (SIC) Generalized RAKE (G-RAKE), Joint Detection (JD) G-RAKE, and Minimum Mean Squared Error (MMSE) G-RAKE. Regardless of the particular receiver architecture adopted, the improved impairment correlations may be used to calculate improved (RAKE) signal combining weights and/or improve channel quality estimates for reporting by receivers operating in Wideband CDMA (W-CDMA) systems transmitting HSDPA channels via MIMO or MISO transmitters. A transmitter may be configured to facilitate impairment correlation determinations by wireless communication receivers operating in MIMO/MISO environments, by signaling one or more values, e.g., data-to-pilot signal transmit power ratios and/or transmit antenna power distributions for the data and pilot signals.

摘要： Interference, such as inter-symbol interference, from a symbol of interest in a RAKE receiver (200) is reduced. The RAKE receiver comprises a plurality of RAKE fingers (220), a processor (230), and a combiner (232). The plurality of RAKE fingers despread symbols received over multiple paths of a multi-path channel. The processor determines cross-correlations between symbol waveforms from different symbols and multiple paths. The combiner combines the despread symbols using the cross-correlations to reduce interference from the symbol of interest.

摘要： In accordance with the invention, signal information representative of a first set of information to be transmitted more than one time over at least one link is stored as a priori known signal information. This could be previously received and/or, detected information, own transmitted information or otherwise available relevant signal information in the node. Signal information representative of a second set of information is received, wherein a transmission of the first set of information interferes with the reception of the second set of information. In spite of the interference, at least part of the second set of information can still be successfully be detected by exploiting the received signal information and at least part of the previously stored a priori known signal information. The information is detected by interference cancellation based on the received signal information and relevant parts of the a priori known information. The set of priori known signal information is preferably updated by continuously storing newly detected information.

摘要： Interference cancellation in a mobile terminal (4) in telecommunication systems like Direct Sequence - Code Division Multiple Access systems or DS-CDMA systems can be improved by providing the mobile terminal (4) with a multi-user detector (41,42,43). These multi-user detectors require the spreading codes of other mobile terminals (2,3,5,6,7,8,9), which spreading codes are available in base stations (1) and thus need to be sent to said mobile terminal (4). By further transmitting power information of other mobile terminals (2,3,5,6,7,8,9) to the mobile terminal (4), a selector (52) can make an intelligent selection in said mobile terminal (4) and select the most important spreading codes thereby reducing the computational complexity. By locating a selector (22) in a base station (1), an intelligent selection can also be made in said base station. Preferably a selection is made per antenna sector and/or in dependence of antenna sectors, in which case direction information of other mobile terminals (2,3,5,6,7,8,9) need to be used.
