  • Orthogonalized spatial multiplexing for wireless communication
    Patent number: 6934320
    Abstract: A method and system for processing information data in a wireless communications system for reducing the complexity in spatial multiplexing of signals over different transmit antennas. In orthogonalized spatial multiplexing with the resolution of one, encoded data are interleaved and converted into a plurality of parallel sub-streams. Each sub-stream is then spreaded with a user specific spreading code with an intentional delay offset of few chips prior to modulating the encoded data for transmission. Likewise, in orthogonalized spatial multiplexing with the resolution of two, encoded data are interleaved and converted into a plurality of parallel sub-stream pairs. Each sub-stream pair is spreaded pairwise with a user specific spreading code with an intentional delay offset of few chips.
