1. An apparatus comprising:

  • a trellis encoder that generates a first symbol and a second symbol;

    a block encoder coupled to receive the first and second symbols and generate a block of symbols, the block of symbols including the first symbol, the second symbol, a complex conjugate of the first symbol and a negative complex conjugate of the second symbol; and

    a first antenna and a second antenna coupled to the block encoder to transmit the block of symbols, the first symbol and the complex conjugate of the first symbol being transmitted with space diversity and with time diversity and the second symbol and the negative complex conjugate of the second symbol being transmitted with space diversity and with time diversity.
