First Claim
Patent Images
1. A spatial modulation method by a transmitting apparatus in a wireless communication system, the spatial modulation method comprising:
- selecting an antenna to send data among transmit antennas arranged to have different polarization angles using a predetermined bit of input data based on indexes of the transmit antenna and mapping remaining bits of the input data to a preset constellation; and
transmitting the remaining bits of the mapped input data through the selected antenna,wherein the selected antenna is estimated by comparing the magnitude of power detected from each of signals received through receive antennas arranged to have different polarization angles, and wherein the input data is demodulated based on information on the estimated antenna.
