1. A method for implementing spatial data processing, the method comprising:

  • selecting a first modulation and coding scheme, MCS, and a second MCS, wherein the selected first MCS comprises a first modulation scheme, and the selected second MCS comprises a second modulation scheme, and wherein the selected second modulation scheme is of higher order than the selected first modulation scheme;

    parsing encoded input data to generate a first spatial stream and a second spatial stream;

    mapping the encoded first spatial stream using the selected first modulation scheme associated with the selected first MCS;

    mapping the encoded second spatial stream using the selected second modulation scheme associated with the selected second MCS;

    performing space time block coding, STBC, on the mapped first spatial stream to generate a first space-time stream, a second space-time stream; and

    performing STBC on the mapped second spatial stream to generate a third space-time stream and a fourth space-time stream, mapping the first space-time stream, the second space-time stream, the third space-time stream, and the fourth space-time stream to a plurality of antennas for transmission.
