摘要： A method of interleaving blocks of indexed data of varying length is disclosed. The method includes the steps of: providing a set of basic Interleavers comprising a family of one or more permutations of the indexed data and having a variable length; selecting one of the basic Interleavers based upon a desired Interleaver length L; and adapting the selected basic Interleaver to produce an Interleaver having the desired Interleaver length L.

摘要： A method of terminating two or more constituent encoders of a turbo encoder employing a turbo code, comprising the step of: generating tail input bits at each of two or more constituent encoders, including deriving the tail input bits from each of the two or more constituent encoders separately from a contents of shift registers within each of the two or more constituent encoders, after an encoding of information bits by the two or more constituent encoders; puncturing one or more tail output bits such that 1/R output tail bits are transmitted for each of a plurality of trellis branches, wherein R is a turbo code rate employed by the turbo encoder during an information bit transmission.; In yet another variation, the step of puncturing the tail output bits further comprises the step of: transmitting, during trellis termination, the tail output bits, only if they are sent from an output branch of one of the two or more constituent encoders that are used during information bit transmission.
摘要翻译：一种终止采用turbo码的turbo编码器的两个或更多个组成编码器的方法，包括以下步骤：在两个或更多个组成编码器中的每一个处产生尾部输入位，包括从两个或更多个成分中的每一个导出尾部输入位在两个或多个组成编码器对信息比特进行编码之后，与两个或更多个组成编码器中的每一个中的移位寄存器的内容分开编码; 对一个或多个尾部输出位进行穿孔，使得对于多个网格分支中的每一个发送1 / R个输出尾比特，其中R是在信息比特传输期间由turbo编码器采用的turbo码率; 在另一个实施例中，打孔尾部输出位的步骤还包括以下步骤：在网格终止期间，仅在从两个或更多个组成编码器之一的输出分支发送尾部输出位时才发送尾部输出位，在信息位传输期间使用。
