Abstract
Methods and systems are disclosed for space interleaved communication of data in a multiple antenna communication system. Data is interleaved over space by interleaving the data over a plurality of transmit branches in the multiple antenna system. The disclosed spatial interleaving increases the performance gains resulting from the spatial transmit diversity of the multiple antenna communication system. Spatial interleaving can be performed, for example, over the bits before the bits are interleaved over frequency. In another variation, spatial interleaving is performed over the symbols after the bits are mapped to symbols.
