Patent ID: 8908793

Claim:
A transmitter comprising: an information processor configured to generate a first information sequence, for a first antenna, based on a first transmission symbol and a first resource index, and a second information sequence, for a second antenna, based on a second transmission symbol and a second resource index different from the first resource index, wherein the first resource index indicates a first resource block and the second resource index indicates a second resource block, which is different from the first resource block; a reference signal generator operatively coupled to the information processor and configured to generate a first reference signal sequence, for the first antenna, based on the first resource index, and a second reference signal sequence, for the second antenna, based on the second resource index; and the first antenna and the second antenna which are respectively configured to simultaneously transmit a first signal generated based on the first information sequence and the first reference signal sequence, and a second signal based on the second information sequence, and the second reference signal sequence.
