METHOD AND DEVICE FOR DEINTERLEAVING INTERLEAVED DATA STREAM IN COMMUNICATION SYSTEM Russian patent published in 2006 - IPC H03M13/27 

Abstract RU 2274951 C2

FIELD: communication systems for high-speed burst data transfer.

SUBSTANCE: proposed method and device are intended for receiving interleaved data and reading recorded characters by way of interleaving in mobile communication system receiver and provide for simultaneous decoding of set of sub-blocks. Interleaved coding burst has m value of bit shift, upper limiting value J, and residue R; character stream of coding burst is recorded in column-line order and in the process intermediate addresses is generated by inverting bit order assuming that residue R equals 0 for characters received; address correction factors are calculated for correcting intermediate address including column produced with residue; read address is generated by adding intermediate address to address correction factor for desired character decoding; character recorded in generated reading address is read out.

EFFECT: enhanced decoding and data transfer speed.
