    • The invention concerns a method and a device for error correction coding associating with a data source series a coded data block, to be transmitted to at least one receiver comprising at least two coding stages (21i) each comprising at least two basic coding modules (22i,j), each of said coding stages receiving a series of data to be processed, distributed between said basic coding modules, and delivering a series of processed data, derived from said basic coding modules and at least one branching stage (23i), said branching stage being inserted between two successive coding stages, a first coding stage and a second coding stage, and distributing the processed data derived from each basic coding module of said first coding stage between at least two basic coding modules of said second stage. The invention also concerns the corresponding decoding method and device, based on path likelihood.

    • The digital circuit is for receiving a master clock signal at a frequency te f on an input and delivering a rectangular shaped output signal at a lower frequency (M/N)f where M is an integer and N is an even integer greater than M. The circuit comprises an even number N of series connected flip-flops in a ring arrangement, each flip-flop being connected to receive input signals from the preceding flip-flop and from the following flip-flop and to receive a master clock signal on a clock input. The even numbered flip-flops are of a type different from the type of the odd numbered flip-flops. The outputs of the flip-flops each deliver a rectangular pulse signal having a duty ratio equal to 1/N of that of the master clock signal. The pulse signals are applied to a combination logic of OR type giving an output signal combining the outputs of said plurality of flip-flops.
    • 数字电路用于以输入端的频率f接收主时钟信号,并以较低频率(M / N)f传送矩形输出信号,其中M为整数,N为大于M的偶数整数。 该电路包括偶数N个以环形布置的串联连接的触发器,每个触发器被连接以接收来自先前触发器和下一个触发器的输入信号,并且接收主时钟信号 时钟输入。 偶数触发器的类型与奇数触发器的类型不同。 触发器的输出各自递送具有等于主时钟信号的占空比的1 / N的矩形脉冲信号。 脉冲信号被施加到或类型的组合逻辑,给出组合所述多个触发器的输出的输出信号。
