Abstract
A multiple-input multiple-output multi-band OFDM transmission system () employs a data interleaving arrangement that is backwards compatible with specifications for a legacy interleaver. In one embodiment, an input data stream is parsed into two or more separate data streams by a round robin parser () and each of the separate data streams is shifted by a corresponding number of symbols and then interleaved by a legacy interleaver (). In another embodiment, data for a plurality (N*i) of symbols is split into N sequential groups of data, each group corresponding to one of N MIMO spatial streams, each stream including data for i symbols. Each group is then interleaved by a legacy interleaver (). In a third embodiment, an input data stream is interleaved by a scaled version of the legacy interleaver (), and then parsed by a round-robin parser ().
