摘要： A deinterleaver for reordering elements of an interleaved digital data sequence (data packet) to obtain an original digital data sequence. The deinterleaver is used in a mobile station operating in a mobile communication system. The interleaved digital data sequence is previously generated by interleaving elements of an original digital data sequence such that digital data elements located in successive positions of the original digital data sequence are located in positions separated by one or more intervening digital data elements in the interleaved digital data sequence. The deinterleaver comprises a data buffer for storing the interleaved digital data sequence; a decoder to generate a first address of a desired data element of the interleaved digital data sequence, the first address corresponding to a position of the desired data element in the original digital data sequence; and an address twister to translate the first address to a second address corresponding to a position of the desired data element in the interleaved digital data sequence; wherein the data buffer is accessed according to the second address to retrieve the desired data element of the original digital data sequence.
