  • System and method for encoding and decoding of space-time block codes in data communication
    Patent number: 8094751
    Abstract: A wireless data communication system. The system includes: a transmitter having a unitary rotation matrix processor for processing incoming information data stream and outputting a plurality of transmission symbols; an encoder for encoding the plurality of transmission symbols; M number of mapper units for mapping the symbols outputted from the encoder into a two dimensional constellation having M data symbols, where M is an integer greater than 1; M number of pulse shaper units to modulate the respective signals from the two dimensional constellation; and M number of antennas to transmit the M data symbols in M time slots. Each antenna transmits a respective symbol from the M symbols in a respective time slot of the M time slots and the encoder is configured to determine which symbol to be transmitted from each antenna in each time slot.
