Interleaving and parsing for MIMO-OFDM systems

摘要: An apparatus ( 150 ) 170 )- 180 ), system 300 and method 200 250 270 280 are provided for a wireless bit-interleaved coded OFDM (BI-COFDM) multiple-in-multiple-out (MIMO) that improves the diversity seen by convolutional decoder. In one embodiment, bit stream is interleaved 202 first, then bits mapped 203 into symbols parsed 204 N t separate streams, where number of transmitters. A deinterleaver 162 performs inverse permutation before sending to Viturbi decoder 163 ). second transmitting side bit-interleaver 176 transforms an encoded punctured using first permutation, groups 175 transformed according desired constellation on antennae, splits streams accordingly bit-interleaves/symbol-maps plurality bit-interleavers/symbol-mappers 174.1 174. permute each permutation. receiving operations side.
