    • The interleaver device comprises a data processor (16) for running an interleaver (I -1 ) under the control of driving means (18), input means (16) for inputting the data set to be interleaved and output means (18) for outputting the interleaved data set. The driving means (18) include mapping processing means (20) for performing a set of bijective elementary functions (φ n ) and supplying a mapping of the interleaver to the data processor (16) for interleaving the data set according to this mapping and interleaver definition means (24) for supplying said mapping processing means, with a definition of said interleaver (I -1 ), expressed as a compound function (φ k o...oφ 1 ) of elementary functions (φ n ), each elementary functions coming from said set of bijective elementary functions (φ n ), for said mapping processing means (20) to perform each of said functions, compounded according to the interleaver definition (I -1 ), and so providing said mapping to the data processor (16).
    • 交织装置包括用于在驱动装置(18)的控制下运行交织器(I-1)的数据处理器(16),用于输入待交织的数据组的输入装置(16)和输出装置(18) 用于输出交错数据集。 驱动装置(18)包括用于执行一组双射基本功能(φn)的映射处理装置(20),并且将交织器的映射提供给数据处理器(16),用于根据该映射和交织器定义交织数据集 用于提供所述映射处理装置的装置(24)与所述交织器(I -1)的定义一起表示为基本函数(φn)的复合函数(φko...oφ1),每个基本函数来自所述 对于所述映射处理装置(20)执行根据交织器定义(I <-1)复合的每个所述功能的一组双射基本函数(φn),并且因此向数据处理器(16)提供所述映射, 。
