    摘要: A transceiver and a data transmission method in a telecommunication system are provided. The transmitter is arranged to transmit a WCDMA signal using one or more antennas, the signal comprising one or more code channels. The transmitter receives as input at least one encoded code channel. The transmitter comprises multipliers (308-314) for spreading each code channel with a spreading code, a combiner (324) for combining the spread signals and a converter (328) for performing a serial-to-parallel conversion on the combined signal, obtaining at least two parallel data streams, each parallel data stream corresponding to a given frequency band used in the transmission, and the transmitter is arranged to transmit the signal using simultaneously at least two different frequency bands.

    摘要: The present invention relates to a method and system for transmitting data in cellular network, wherein frequency reuse is proposed to be designed adaptive and utilized only only when needed, e.g., with small coding rates. The adaptive reuse can be obtained by using the conventional link adaptation approach. The invention can be easily applied to a Frequency Division Multiple Access (FDMA) system which consists of combination of localized and distributed FDMA. Thereby, better resistance against strong other cell interference can be provided.

    摘要: An interference cancellation unit having as an input two or more IFDMA signals comprising a multitude of frequency bins is provided. The unit comprises a channel estimator for determining a channel estimate from the input signals, a matrix calculator for determining an error covariance matrix of the input signals, and an estimator for determining weight factors on the basis of the channel estimate and the error covariance matrix and weighting and combining the input signals. The unit further comprises a preprocessor for removing unwanted frequency bins from the input signals prior to the error covariance calculation.
