Abrégé
(EN)
A device for sequentially storing input bit symbols of a given interleaver size N in a memory at an address from 1 to N and reading the stored bit symbols from the memory. The device comprises a look-up table for providing a first variable m and a second variable J satisfying the equation N=2<m>xJ; and an address generator for generating a read address depending on the first and second variables m and J provided from the look-up table. The read address is determined by 2<m>(K mod J) + BRO(K/J), where K(0<=K<=(N-1)) denotes a reading sequence and BRO is a function for converting a binary value to a decimal value by bit reversing.

一种在存储器中从1到N的地址处顺序存储给定交织器尺寸N的输入比特符号,并从该存储器中读取存储的比特符号的设备,该设备包括:一表,用于存储满足等式N=2m×J的第一变量m和第二变量J;和一地址产生器,用于依据从表存储的第一和第二变量m和J产生一读地址。该读地址是由表达式2m(K mod J)+BRO(K/J)来确定的,其中K(0≤K≤(N-1))表示读取序列,并且BRO是用于通过比特反向将二进制值转换为十进制值的函数。
