    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.
