Title:
インタリーバ及びデインタリーバシステム
Document Type and Number:
Japanese Patent JP4296172
Kind Code:
B2
Abstract:
This invention relates to bit interleaver and de-interleaver apparatus, methods and processor control code for use in MIMO (Multiple-input multiple-output) communications systems, in particular MIMO systems employing OFDM (orthogonal frequency division multiplexing). We describe an interleaver for a MIMO OFDM communications system having a plurality of transmit antennas, said interleaver being configured to interleave a block of N data bits comprising data for a plurality of OFDM symbols, each OFDM symbol being defined by a block of Ncbps bits, by implementing first and second interleaving functions wherein at least one of said interleaving finctions is configured to interleave data bits between said blocks of Ncbps bits. We also describe a corresponding de-interleaver and related interleaving and de-interleaving methods.
