    • A method of and apparatus for matching a rate of data bits, in a matrix of data bits interleaved by a predetermined interleaving process, to a desired rate by deletion of redundant data bits or repetition of data bits derived from the matrix, includes steps of determining in a non-interleaved matrix of the data bits a pattern of bits to be deleted or repeated to provide the desired data rate, decoding an address of each bit in said pattern in a manner inverse to the interleaving process to produce a respective address of the bit in the matrix of interleaved data bits, and deleting or repeating the respective bit in the interleaved data bits in dependence upon the respective address. The address decoding is performed in the same manner as a coding of addresses for producing the interleaved data bits from the non-interleaved matrix of the data bits. The specification also discloses an advantageous interleaving process for channel interleaving in a 3rd generation CDMA wireless communications system, a shuffling method for a second stage of interleaving in such a system, and how the rate matching can be conveniently applied to turbo-coded data.
    • 一种方法和装置,用于通过删除冗余数据位或从该矩阵导出的数据比特的重复,将由预定交织处理交织的数据比特矩阵中的数据比特速率匹配到期望速率,包括以下步骤:确定 在数据比特的非交织矩阵中,要删除或重复的比特模式以提供期望的数据速率,以与交织处理相反的方式对所述模式中的每个比特的地址进行解码,以产生相应的地址 并且根据相应的地址删除或重复交织的数据比特中的各个比特。 以与用于从数据比特的非交织矩阵产生交错数据比特的地址的编码相同的方式执行地址解码。 本说明书还公开了一种用于第三代CDMA无线通信系统中的信道交织的有利的交织过程,在这种系统中用于第二级交织的混洗方法,以及如何将速率匹配方便地应用于turbo编码数据。

    • An apparatus and method for reading written symbols by deinterleaving to decode a written encoder packet in a receiver for a mobile communication system supporting turbo coding and interleaving, such that a turbo-coded/interleaved encoder packet has a bit shift value m, an up-limit value J and a remainder R, and a stream of symbols of the encoder packet is written in order of column to row. The apparatus and method perform the operations of generating an interim address by bit reversal order (BRO) assuming that the remainder R is 0 for the received symbols; calculating an address compensation factor for compensating the interim address in consideration of a column formed with the remainder; and generating a read address by adding the interim address and the address compensation factor for a decoding-required symbol, and reading a symbol written in the generated read address.

    • Systems (1) with interleavers (2) for interleaving data units and with de-interleavers (3) for de-interleaving data units, are made more efficient and less complex by storing data units in the form of stacks in the memories (29,39) of said interleavers (2) and said de-interleavers (3), by calculating stack positions for data units to be (de)interleaved, and by adapting stacks through shifting before the interleaving or after the de-interleaving. Such a system (1) does not require more than null(Nnull1)(Dnull1)null/2 memory elements, the theoretical memory size for the block length N and the interleaving depth D. Said data units are stored at subsequent positions, with said data units at said subsequent positions being adapted through shifting before the interleaving or after the de-interleaving to further subsequent positions. An interleaver (2) comprises a calculator (21), a shifter (23) and an inserter (24). A de-interleaver (3) comprises a calculator (31), an extracter (34) and a shifter (33).
